Abstract
Moringa oleifera is a local plant which is commonly used in cooking and as a health supplement. It has been reported to possess blood pressure (BP) lowering effect and little is known about its possible interactions with cardiovascular drugs. This study looked into the possible drug-herb interactions between M. oleifera leaves extract and selected antihypertensive drugs. Ten groups of spontaneously hypertensive rats (SHRs) and one group of normotensive rats (NTs) were administered either M. oleifera extract alone, drugs alone or drugs in combination with M. oleifera extract for 14 days and BP of the rats were measured. Angiotensin converting enzyme (ACE) activity was also determined in vitro and ex vivo. Treated groups were found to produce significant BP reduction on day 15 when compared with the negative control but there was no significance difference when compared with positive controls (drugs alone). M. oleifera extract administered alone significantly reduced BP of SHRs on day 15 and this is comparable with the BP reduction observed when antihypertensive drugs were administered alone. However, no additive effect was observed when drugs were used in combination with M. oleifera extract. Similar results were seen in the in vitro and ex vivo ACE inhibitory activity of M. oleifera extract and enalapril. It can be concluded that there is a possibility of drug-herb interaction between M. oleifera extract and the selected antihypertensive drugs.

Abstract
Purpose: To investigate the blood pressure-lowering effect of green tea (GT) extract alone and in combination with an angiotensin converting enzyme (ACE) inhibitor, perindopril, on rats.
Methods: The study consisted of four groups of five spontaneously hypertensive rats (SHR): negative control (2 % tragacanth mucilage), positive control group (perindopril, 0.36 mg/kg/day) and two treatment groups (green tea, 25 mg/kg/day; and combined green tea/perindopril). The treatments were given orally for 14 days. Systolic blood pressure was measured before and after treatment using the tail cuff technique. Angiotensin converting enzyme activity in the lung homogenate of the hypertensive rats was determined spectrophotometrically.
Results: Green tea extract significantly reduced the rats’ systolic blood pressure (p < 0.05) but did not inhibit the angiotensin-converting enzyme. The combination of green tea extract with perindopril also caused a significant decline in blood pressure (p < 0.001). However, the green tea extract attenuated the inhibition of the angiotensin-converting enzyme activity by perindopril.
Conclusion: Green tea extract produces anti-hypertensive activity in rats, but its mechanism of action is not via inhibition of angiotensin-converting enzyme. The interaction of GT extract with perindopril results in a reduction of ACE inhibitory activity.

Abstract
Purpose: To investigate the inhibitory effects of a chalcone derivative on lipopolysaccharide (LPS)- induced interleukin (IL)-6 and IL-8 secretions and on LPS-induced mitogen-activated protein kinases (MAPK) and nuclear factor kappa B (NF-κB) activation in human U937 macrophage-like cell line.
Methods: The effects of chalcone derivative on LPS-induced secretion of IL-6 and IL-8 in endothelial cells were determined by enzyme-linked immunosorbent assay while the effects of chalcone on the activation of MAPK and NF-kB pathway were determined by Western blotting.
Results: The results showed that 3-(5-methyl-furan-2-yl)-naphthalen-1-yl-propenone (compound 1) significantly inhibited the secretion of LPS-induced IL-6 and IL-8 in U937 macrophages. This compound also demonstrated significant suppression of c-Jun N-terminal kinases (JNK) and extracellular signalregulated kinases (ERK) phosphorylation. However, the compound did not reverse the degradation of inhibitor kappa B alpha (IκBα) and did not inhibit the phosphorylation of NF-κB subunit and P-38 MAPK.
Conclusion: Compound 1 inhibits the secretion of cytokines via the inhibition of ERK and JNK pathways. These results suggest that chalcone derivative could act as an antiinflammatory agent by altering cytokine secretion and inflammatory pathways.

Abstract
Inflammation is a body response towards any injury or tissue damage. It involves the accumulation of neutrophils and release of inflammatory mediators. ANXA1, a 37 kDa glucocorticoid inducible protein plays an important role in resolving inflammation. The unique N-terminal and its mimetic peptide exert strong anti-inflammatory actions. This study was conducted to review the roles of ANXA1 in inflammation and identify any other reported roles. Electronic search was done whereby a total of 3797 articles were located from three databases, namely Ovid MEDLINE, Science Direct, and PubMed. Articles on ANXA1 and inflammation were selected based on inclusive criteria and review papers were excluded. Bias analysis was performed based on bias risk tool and 27 articles were included in the study. It was found that ANXA1 was able to resolve inflammation in many inflammatory diseases. Upon treatment with glucocorticoid, ANXA1 is induced and its significant expressions in tissues are important in resolving inflammation. However, this effect can be reversed by administering an anti-annexin antibody. This protein also acts on members of all formyl peptide receptors (FPR) and activates them to initiate reaction. It acts mainly by causing the death of neutrophils through apoptosis. In addition, ANXA1 is identified as a marker in cancer cells which determines the survival rates. In conclusion, ANXA1 is a key modulator in resolving inflammation in many diseases and is actively being induced upon glucocorticoid treatment.

Abstract
Background Phytoestrogens are polyphenolic plant compounds which are structurally similar to the endogenous mammalian estrogen, 17β-estradiol. Annexin A1 (ANXA1) is an endogenous protein which inhibits cyclo-oxygenase 2 (COX-2) and phospholipase A2, signal transduction, DNA replication, cell transformation, and mediation of apoptosis. Objective This study aimed to determine the effects of selected phytoestrogens on annexin A1 (ANXA1) expression, mode of cell death and cell cycle arrest in different human leukemic cell lines. Methods Cells viability were examined by MTT assay and ANXA1 quantification via Enzyme-linked Immunosorbent Assay. Cell cycle and apoptosis were examined by flow cytometer and phagocytosis effect was evaluated using haematoxylin-eosin staining. Results Coumestrol significantly (p < 0.05) reduced the total level of ANXA1 in both K562 and U937 cells and genistein significantly (p < 0.05) reduced it in K562, Jurkat and U937 cells, meanwhile estradiol and daidzein induced similar reduction in U937 and Jurkat cells. Coumestrol and daidzein induced apoptosis in K562 and Jurkat cells, while genistein and estradiol induced apoptosis in all tested cells. Coumestrol and estradiol induced cell cycle arrest at G2/M phase in K562 and Jurkat cells with an addition of U937 cells for estradiol. Genistein induced cell cycle arrest at S phase for both K562 and Jurkat cells. However, daidzein induced cell cycle arrest at G0/G1 phase in K562, and G2/M phase of Jurkat cells. Coumestrol, genistein and estradiol induced phagocytosis in all tested cells but daidzein induced significant (p < 0.05) phagocytosis in K562 and Jurkat cells only. Conclusion The selected phytoestrogens induced cell cycle arrest, apoptosis and phagocytosis and at the same time they reduced ANXA1 level in the tested cells. The IC50 value of phytoestrogens was undetectable at the concentrations tested, their ability to induce leukemic cells death may be related with their ability to reduce the levels of ANXA1. These findings can be used as a new approach in cancer treatment particularly in leukemia.

Abstract
Currently, treatments for dengue infection are only symptomatic as no antiviral agents nor vaccines are available to combat this virus. Despite challenges faced by researchers, many efforts are ongoing to reduce cases of dengue infection either by targeting the vector or the virus. Vector population is monitored and reduced by using mechanical, chemical and biological controls. Chemical control is achieved either by using synthetic or natural insecticides where the latter is more preferable. In biological control, bacteria, fungi and larvivorous fish are utilised to reduce the vector population. Moreover, genes of mosquitoes are also explored to produce progenies which are sterile with low survival ability. Vaccines are among the most effective ways to prevent viral infection. Various approaches have been used and are still being explored towards producing vaccines for dengue. These include live attenuated, inactivated, recombinant subunit, nucleic acid and virus-like particles vaccines. The aim is to produce a vaccine which can target all the four serotypes of the virus. Monoclonal antibodies are widely researched on to equip the host defense mechanism against the dengue virus. Deeper understanding of the virus replication cycle warrants the development of antiviral agents which target viral proteins vital for the replication process. Bioactive compounds are also utilised in the development of antiviral agents. The importance of surveillance and supportive therapy are also discussed.

Abstract
BACKGROUND Phytoestrogens are plant compounds that are structurally similar to estrogen and that possess anti-cancer properties. Previous studies have reported that coumestrol, daidzein and genistein could induce cell death by reducing Annexin A1 protein in leukemic cell lines. Annexin A1 (ANXA1) is involved in cell progression, metastasis, and apoptosis in several types of cancer cells. The present study sought to investigate if the effects of phytoestrogens on apoptosis, cell cycle arrest and phagocytosis in ANXA1-knockdown leukemic cells are mediated through ANXA1 or occurred independently. METHODS Transfection of ANXA1 siRNA was conducted to downregulate ANXA1 expression in Jurkat, K562 and U937 cells. Apoptosis and cell cycle assays were conducted using flow cytometry. Western blot was performed to evaluate ANXA1, caspases and Bcl-2 proteins expression. Phagocytosis was determined using hematoxylin and eosin staining. RESULTS The expression of ANXA1 after the knockdown was significantly downregulated in all cell lines. Genistein significantly induced apoptosis associated with an upregulation of procaspase-3, -9, and - 1 in Jurkat cells. The Bcl-2 expression showed no significant difference in Jurkat, K562 and U937 cells. Treatment with phytoestrogens increased procaspase-1 expression in Jurkat and U937 cells while no changes were detected in K562 cells. Flow cytometry analysis demonstrated that after ANXA1 knockdown, coumestrol and genistein caused cell cycle arrest at G2/M phase in selected type of cells. The percentage of phagocytosis and phagocytosis index increased after the treatment with phytoestrogens in all cell lines. CONCLUSION Phytoestrogens induced cell death in ANXA1-knockdown leukemia cells, mediated by Annexin A1 proteins. Graphical abstract.

Abstract
Background Moringa oleifera Lam. is a commonly used plant in herbal medicine and has various reported bioactivities such as antioxidant, antimicrobial, anticancer and antidiabetes. It is rich in nutrients and polyphenols. The plant also has been traditionally used for alleviating allergic conditions. This study was aimed to examine the anti-allergic activity of M. oleifera extracts and its isolated compounds. Method M. oleifera leaves, seeds and pods were extracted with 80% of ethanol. Individual compounds were isolated using a column chromatographic technique and elucidated based on the nuclear magnetic resonance (NMR) and electrospray ionisation mass spectrometry (ESIMS) spectral data. The anti-allergic activity of the extracts, isolated compounds and ketotifen fumarate as a positive control was evaluated using rat basophilic leukaemia (RBL-2H3) cells for early and late phases of allergic reactions. The early phase was determined based on the inhibition of beta-hexosaminidase and histamine release; while the late phase was based on the inhibition of interleukin (IL-4) and tumour necrosis factor (TNF-α) release. Results Two new compounds; ethyl-(E)–undec-6-enoate (1) and 3,5,6-trihydroxy-2-(2,3,4,5,6-pentahydroxyphenyl)-4H-chromen-4-one (2) together with six known compounds; quercetin (3), kaempferol (4), β-sitosterol-3-O-glucoside (5), oleic acid (6), glucomoringin (7), 2,3,4-trihydroxybenzaldehyde (8) and stigmasterol (9) were isolated from M. oleifera extracts. All extracts and the isolated compounds inhibited mast cell degranulation by inhibiting beta-hexosaminidase and histamine release, as well as the release of IL-4 and TNF-α at varying levels compared with ketotifen fumarate. Conclusion The study suggested that M. oleifera and its isolated compounds potentially have an anti-allergic activity by inhibiting both early and late phases of allergic reactions.

Abstract
BACKGROUND Preference for herbal use is increasing worldwide. This is especially true for Malay women in Malaysia that is steeped in traditional and cultural values and surrounded by diverse flora. However, concerns arise with the use of herbs due to the lack of monitoring, scientific evidence and risk of adverse effects. As such identifying potential herbal users is vital to ensure appropriate management is optimised. OBJECTIVE This study derives insights on preferred herbs, perception and predictors of herbal use for health among Malay women in Malaysia. METHODS This was a cross-sectional survey, comprising of Malay women, performed in all fourteen states in Malaysia. Respondents were assessed for demographic characteristic, current use of herbal medicine, their preferred herbal medicine and perception of herbal use. Predictors of herbal use were then determined using a multivariate logistic regression model. RESULTS A total of 1067 respondents were included in the study of which 592 (55.5%) admitted to using herbs for health. In general, raw herbs were the most preferred herbal remedies used (n=407, 69.5%). A significantly higher number of respondents perceived that herbal remedies would not cause any problems to women's overall health (n=725, 67.9%) (χ2=137.5, df(1), p<0.001), although a large majority agreed that not all remedies were safe for pregnant women (n=979, 91.8%) (χ2=744.03, df(1), p<0.001). Among predictors of herbal use were marital status and income (χ2=203.98, df(795) p<0.001). Those that were married were 3.9 times more likely to use herbs than unmarried women (p<0.001). Having an income of <RM 3000 or USD 729 increased the odds of using herbs among women by 6.2 times compared to their counterparts (p<0.001). CONCLUSION The current findings provide an insight into specific groups, information and health initiatives that can be targeted to strengthen herbal use monitoring among Malay women.

Abstract
Tuberculosis, caused by Mycobacterium tuberculosis, is amongst the foremost infectious diseases. Treatment of tuberculosis is a complex process due to various factors including a patient's inability to persevere with a combined treatment regimen, the difficulty in eradicating the infection in immune-suppressed patients, and multidrug resistance (MDR). Extensive research circumscribing molecules to counteract this disease has led to the identification of many inhibitory small molecules. Among these are chalcone derivatives along with curcumin analogs. In this review article, we summarize the reported literature regarding anti tubercular activity of chalcone derivatives and synthetic curcumin analogs. Our goal is to provide an analysis of research to date in order to facilitate the synthesis of superior antitubercular chalcone derivatives and curcumin analogs.

Abstract
Chalcones are the principal precursors for the biosynthesis of flavonoids and isoflavonoids. A three carbon α, β-unsaturated carbonyl system constitutes chalcones. Chalcones are the condensation products of aromatic aldehyde with acetophenones in attendance of catalyst. They go through an assortment of chemical reactions and are found advantageous in synthesis of pyrazoline, isoxazole and a variety of heterocyclic compounds. In synthesizing a range of therapeutic compounds, chalcones impart key role. They have showed worth mentioning therapeutic efficacy for the treatment of various diseases. Chalcone based derivatives have gained heed since they own simple structures, and diverse pharmacological actions. A lot of methods and schemes have been reported for the synthesis of these compounds. Amongst all, Aldol condensation and Claisen-Schmidt condensation still grasp high up position. Other distinguished techniques include Suzuki reaction, Witting reaction, Friedel-Crafts acylation with cinnamoyl chloride, Photo-Fries rearrangement of phenyl cinnamates etc. These inventive techniques utilize various catalysts and reagents including SOCl(2) natural phosphate, lithium nitrate, amino grafted zeolites, zinc oxide, water, Na(2)CO(3), PEG400, silicasulfuric acid, ZrCl(4) and ionic liquid etc. The development of better techniques for the synthesis of α, β- unsaturated carbonyl compounds is still in high demand. In brief, we have explained the methods and catalysts used in the synthesis of chalcones along with their biological activities in a review form to provide information for the development of new-fangled processes targeting better yield, less reaction time and least side effects with utmost pharmacological properties.

Abstract
Chalcones (1, 3-Diphenyl-2-propen-1-one) are constituted by a three carbon α, β-unsaturated carbonyl system. The biosynthesis of flavonoids and isoflavonoids is initiated by chalcones. Notable pharmacological activities of chalcones and its derivatives include anti-inflammatory, antifungal, antibacterial, antimalarial, antituberculosis, antitumor, antimicrobial and antiviral effects respectively. Owing to simplicity of the chemical structures and a huge variety of pharmacological actions exhibited, the entities derived from chalcones are subjected to extensive consideration. This review article is an effort to sum up the anti-inflammatory activities of chalcone derived chemical entities. Effect of chalcones on lipid peroxidation, heme oxygenase 1(HO-1), cyclooxygenase (COX), interleukin 5 (IL-5), nitric oxide (NO) and expression of cell adhesion molecules (CAM) is summarized stepwise.

Abstract
A series of novel isoxazole and pyrazoline derivatives has been synthesized and evaluated for their effects on the chemiluminescence and chemotactic activity of human phagocytes. Their effects on the chemotactic migration of isolated polymorphonuclear leukocytes (PMNs) and on the release of reactive oxygen species (ROS) during respiratory burst of human whole blood and PMNs were carried out using the Boyden chamber technique and luminol-based chemiluminescence assay, respectively. Of the compounds tested, compounds 8, 9, 11 and 12 exhibited higher inhibitory activity on the release of ROS (with IC50 values ranging from 5.6 to 8.4 μM) than acetylsalicylic acid (IC50 = 9.5 μ M). These compounds also showed strong inhibitory activity on the migration of PMNs with compound 8 exhibiting an IC50 value lower than that of ibuprofen. The results suggest that some of these isoxazole and pyrazoline derivatives have ability to modulate the innate immune response of phagocytes at different steps, indicating their potential as a source of new immunomodulatory agents.

Abstract
Acetylmelodorinol, chrysin and polycarpol, together with benzoic acid, benzoquinone and stigmasterol were isolated from the leaves of Mitrella kentii (Bl.) Miq. The compounds were evaluated for their ability to inhibit prostaglandin E2 (PGE2) and thromboxane B2 (TXB2) production in human whole blood using a radioimmunoassay technique. Their inhibitory effect on platelet activating factor (PAF) receptor binding to rabbit platelet was determined using 3H-PAF as a ligand. Among the compounds tested, chrysin showed a strong dose-dependent inhibitory activity on PGE2 production (IC50 value of 25.5 µM), which might be due to direct inhibition of cyclooxygenase-2 (COX-2) enzymatic activity. Polycarpol, acetylmelodorinol and stigmasterol exhibited significant and concentration-dependent inhibitory effects on TXB2 production with IC50 values of 15.6, 19.1 and 19.4 µM, respectively, suggesting that they strongly inhibited COX-1 activity. Polycarpol and acetylmelodorinol showed strong dose-dependent inhibitory effects on PAF receptor binding with IC50 values of 24.3 and 24.5 µM, respectively.

Abstract
OBJECTIVES A series of 43 curcumin diarylpentanoid analogues were synthesized and evaluated for their inhibitory effects on the chemiluminescence and chemotactic activity of phagocytes in vitro. METHODS The effects of the compounds on the respiratory burst of human whole blood and isolated human polymorphonuclear leukocytes (PMNs) were evaluated using a luminol-based chemiluminescence assay and their effect on chemotactic migration of PMNs was investigated using the Boyden chamber technique. KEY FINDINGS Compounds 6, 17, 25 and 30 exhibited significant inhibitory activity on the oxidative burst of PMNs. The presence of methoxy groups at positions 2 and 5, and methoxylation and fluorination at positions 4 and 2 of both phenyl rings, respectively, may contribute significantly to their reactive oxygen species inhibition activity. Compounds 7, 17, 18, 24 and 32 showed strong inhibition of the chemotaxis migration of PMNs. Chlorination at various positions of both phenyl rings of cyclohexanone diarylpentanoid resulted in compounds with potent inhibitory effects on PMN migration. CONCLUSIONS The results suggest that some of these diarylpentanoid analogues are able to modulate the innate immune response of phagocytes at different steps, emphasizing their potential as a source of new immunomodulatory agents.

Abstract
Acyclic nucleosides have been of considerable interest since the approval of aciclovir by the FDA to be used as an antiviral agent in the 1990s. The acyclic moieties and the bases used in the experiment were either available commercially or synthesized using literature methods. Vorbruggen coupling method was utilized involving reaction of persilylated heterocyclic bases with the appropriate acyclic moiety in the presence of a Lewis acid catalyst. A series of novel 6-azapyrimidine acyclic oxosugar nucleosides was successfully synthesized with a promising yield (more than 50%). An efficient method of protection and deprotection was also investigated.

Abstract
The synthesis of dideoxy-6-azathymidine 4'-thionucleoside 1-(2,3-dideoxy-4-thio-beta-D-erythro-pentofuranosyl)-(6-azathymidine) (2), and the L-nucleoside, 1-(4-thio-beta-L-erythro-pentofuranosyl)-(6-azathymidine) (3) and their evaluation against a wide panel of antiviral assays are described. The L-thionucleoside (3) was devoid of antiviral activity. The dideoxy-thionucleoside (2) was moderately active against vaccinia virus (VV) and the herpes simplex virus strains HSV-1 (strain KOS) and HSV-2 (strain G) (MIC 12 microM) and retained inhibitory activity vs a thymidine kinase-deficient strain HSV-1/TK(-), suggesting that (2) is not dependent on viral TK-catalysed phosphorylation for antiviral activity and/or may use an alternative metabolic activation pathway.

Abstract
A study on the use of 3'-directing groups for the synthesis of imidazole 2'-deoxy-4'-thionucleosides led to varying alpha:beta ratios in the glycosylation reaction. The para-nitrobenzoyl group gave the optimum result in the glycosylation step; therefore, this protected thiosugar 10b was used for the synthesis of a series of novel 2'-deoxy-4'-thio-imidazole nucleosides which have been evaluated for antiviral activity in vitro.

Abstract
A study on the use of protecting groups led to the employment of the para-methoxybenzoyl (pMB) group as a directing group in the synthesis of novel triazole 2'-deoxy-4'-thionucleosides. Use of the pMB group gave alpha:beta ratios of 1:6 in the glycosylation step with azidotrimethylsilane. A series of novel triazoles were generated for in vitro antiviral evaluation.
