Abstract
Multiple inhibitions of CA, COX-2 and 5-LOX enzymes has been recognised as a useful strategy for the development of anti-inflammatory drugs that can avoid the disadvantages of using NSAIDs alone. Here, we report new pyridazine-based sulphonamides (5a-c and 7a-f) as potential multi-target anti-inflammatory candidates. First, the furanone heterocycle in the dual CA/COX-2 inhibitor Polmacoxib was replaced with the pyridazinone one. Then, a hydrophobic tail was appended through benzylation of the 3-hydroxyl group of the pyridazinone scaffold to afford benzyloxy pyridazines 5a-c. Furthermore, the structures were adorned with the polar sulphonate functionality, in pyridazine sulphonates 7a-f, that are expected to be engaged in interactions with the hydrophilic half of the CA binding sites. All of the disclosed pyridazinones were tested for inhibitory activities against 4 hCA isoforms (I, II, IX, and XII), as well as against COX-1/2, and 5-LOX. Furthermore, in vivo anti-inflammatory and analgesic effects of pyridazinones 7a and 7b were examined.

Abstract
PURPOSE This work aimed to fabricate alginate based in-situ gelling matrix of vildagliptin improved by calcium and carboxy methyl cellulose (CMC) for appropriate adjustment of the onset and duration of action. This easy-to-swallow thickened liquid preparation aimed to improve compliance for dysphagic or elderly diabetic patients. METHODS Vildagliptin dispersions containing alginate were fabricated in the presence or absence of calcium chloride to assess the effect of calcium ion, then a matrix containing 1.5% w/v of sodium alginate with calcium was further examined after the addition of CMC with different concentrations ranging from 0.1% to 0.3%. The viscosity, gelling forming property, Differential scanning calorimetry, and in-vitro drug release were assessed before monitoring the hypoglycemic effect of the selected formulation. RESULTS In-situ gel matrixes were fabricated at gastric pH with and without calcium ions. The best formula concerning viscosity and the gel-forming property was achieved with higher CMC concentrations, which in turn decreased the rate of vildagliptin release in stimulated gastric pH. In-vivo results confirmed the extended hypoglycemic effect of the vildagliptin in-situ gelling matrix compared to the vildagliptin aqueous solution. CONCLUSION This study represents a green polymeric-based in-situ gel as a liquid oral retarded release preparation intended for reducing dose frequency, easier administration of vildagliptin, and improving compliance in geriatric and dysphagic diabetic patients.

Abstract
In the current medical era, the single target inhibition paradigm of drug discovery has given way to the multi-target design concept. As the most intricate pathological process, inflammation gives rise to a variety of diseases. There are several drawbacks to the single target anti-inflammatory drugs currently available. Herein, we present the design and synthesis of a novel series of 4-(5-amino-pyrazol-1-yl)benzenesulfonamide derivatives (7a-j) with COX-2, 5-LOX and carbonic anhydrase (CA) inhibitory activities as potential multi-target anti-inflammatory agents. The pharmacophoric 4-(pyrazol-1-yl)benzenesulfonamide moiety in Celecoxib was used as the core scaffold and different substituted phenyl and 2-thienyl tails were grafted via a hydrazone linker to enhance inhibitory activity against hCA IX and XII isoforms, yielding target pyrazoles 7a-j. All reported pyrazoles were evaluated for their inhibitory activity against COX-1, COX-2, and 5-LOX. Pyrazoles 7a, 7b, and 7j showed the best inhibitory activities against the COX-2 isozyme (IC50 = 49, 60 and 60 nM, respectively) and against 5-LOX (IC50 = 2.4, 1.9, and 2.5 μM, respectively) with excellent SI indices (COX-1/COX-2) of 212.24, 208.33, and 158.33, respectively. In addition, the inhibitory activities of pyrazoles 7a-j were evaluated against four different hCA isoforms I, II, IX, and XII. Both transmembrane hCA IX and XII isoforms were potently inhibited by pyrazoles 7a-j with KI values in the nanomolar range; 13.0-82.1 nM and 5.8-62.0 nM, respectively. Furthermore, pyrazoles 7a and 7b with the highest COX-2 activity and selectivity indices were evaluated in vivo for their analgesic, anti-inflammatory, and ulcerogenic activities. The serum level of the inflammatory mediators was then measured in order to confirm the anti-inflammatory activities of pyrazoles 7a and 7b.

Abstract
A new series of co-drugs was designed based on hybridising the dihydropteroate synthase (DHPS) inhibitor sulphonamide scaffold with the COX-2 inhibitor salicylamide pharmacophore through biodegradable linkage to achieve compounds with synergistic dual inhibition of COX-2/PGE2 axis and DHPS enzyme to enhance antibacterial activity for treatment of septicaemia. Compounds 5 b, 5j, 5n and 5o demonstrated potent in vitro COX-2 inhibitory activity comparable to celecoxib. 5j and 5o exhibited ED50 lower than celecoxib in carrageenan-induced paw edoema test with % PGE2 inhibition higher than celecoxib. Furthermore, 5 b, 5j and 5n showed gastric safety profile like celecoxib. Moreover, in vivo antibacterial screening revealed that, 5j showed activity against S.aureus and E.coli higher than sulfasalazine. While, 5o revealed activity against E.coli higher than sulfasalazine and against S.aureus comparable to sulfasalazine. Compound 5j achieved the target goal as potent inhibitor of COX-2/PGE2 axis and in vivo broad-spectrum antibacterial activity against induced septicaemia in mice.

Abstract
BACKGROUND The different parts of pomegranate fruit are considered a powerful mixture of bioactive compounds yet the peels and pulps of the fruits are usually discarded and considered as industrial waste. In this work, ultra-performance liquid chromatography coupled with triple quadrupole mass spectrometry (UPLC-QqQ-MS) was utilized for metabolomics analysis of different parts (peel, pulp, seed and juice) of pomegranate fruit cultivars to verify possible variations among the fruits and their waste products as potential sources of functional constituents. RESULTS Orthogonal projection to latent structure-discriminant analysis (OPLS-DA) coefficient-plot showed enrichment of phenolic compounds such as punicalagin and ellagic acid derivatives in pulp samples while seeds class was enriched in phlorizin, catechin and quercetin, juice class showed abundance of naringenin and pelargonidin-3-pentoside while peels were enriched in anthocyanins and flavonoids including cyanidin diglycoside, quercetin and luteolin glycosides. Although the juice samples of almost all tested cultivars showed remarkable cytotoxic activity, the pulp samples, particularly the Manfalouti cultivar, exhibited the most potent [half maximal inhibitory concentration (IC50 ) = 2.367 ± 0.14 μg/mL in MCF-7, IC50 = 3.854 ± 0.23 μg/mL in Hep-G2 cell lines]. OPLS models were constructed for determination of cytotoxicity-associated metabolites among where the coefficients plots revealed tannins; granatin A, ellagic acid derivatives, punicalagin α and β, in addition to anthocyanins and phenolic compounds; cyanidin diglycoside, quercetin, phlorizin, 3-O-caffeoylquinic acid, naringenin and liquiritin were more pertinent with cytotoxicity of the different parts of pomegranate fruit. CONCLUSION The results obtained allow for the full utilization of the resources of pomegranate fruit and its industrial waste as sources of bioactive compounds. © 2022 Society of Chemical Industry.

Abstract
Despite considerable advances in cancer treatment, chemotherapy remains a cornerstone in breast cancer therapy. Therefore, reducing chemoresistance and adverse effects of chemotherapy is a priority. In this regard, Baicalin (BA) is the dominant natural flavonoid extracted from the roots of Scutellaria baicalensis showed fascinating antitumor activity in many types of cancers, including breast cancer. The present study aimed to explore the chemopreventive and antitumor action of baicalin alone and in combination with 5-FU in addition to its ability to enhance the antitumor effect of 5-FU on breast cancer using the Ehrlich solid tumor-mice model. MATERIALS AND METHODS A total of 70 female mice were divided into seven groups (1st group, saline group; 2nd group, DMSO group; 3rd group, BA+EST group; 4th group, EST group; 5th group, EST+5-FU; 6th group, EST+BA group; 7th group, EST+5-FU+BA).tumors were assessed by weight and histopathological examination. Inflammation, angiogenesis, and apoptosis were examined by ELISA, qRT-PCR, and immunohistochemical examinations. RESULTS showed that pre-treatment with baicalin and treatment with baicalin and/or 5-FU significantly reduced inflammation and angiogenesis indicated by suppression of NF-kB/ IL-1β and VEGF amplification loop with marked elevation in apoptosis indicated by up-regulation of apoptotic caspase-3, pro-apoptotic p53, Bax and downregulation of anti-apoptotic Bcl-2. CONCLUSION BA is a promising preventive or adjuvant therapy in breast cancer treatment with 5-FU mainly via cooperative inhibition of inflammation, angiogenesis, and triggering apoptotic cell death.

Abstract
Rosmarinic acid is a natural polyphenolic compound that is found in different plant species and used for different medicinal purposes. This study aimed to investigate the chemo-preventive effect of rosmarinic acid and evaluate its antitumor efficacy alone or in combination with Paclitaxel in breast cancer mice model. Ehrlich induced mice mammary solid tumor model was used in the study. Mice were treated with oral rosmarinic acid and intraperitoneal Paclitaxel. Inflammation, angiogenesis, and apoptosis were checked. Enzyme linked immunosorbent assay (ELISA), quantitative real time PCR, and immunohistochemical methods were performed. Rosmarinic acid used prior to tumor induction suppressed NF-κB, TNF-α, vascular endothelial growth factor (VEGF) serum levels, and VEGF receptors. It also triggered apoptosis by restoring the levels of P53, Bcl-2, Bax, and caspase-3. Furthermore, in Ehrlich solid tumor mice, rosmarinic acid, and/or Paclitaxel significantly suppressed tumor growth with an increase in apoptotic markers P53 and Caspase-3 levels, and suppressed the Bcl2/Bax ratio. Rosmarinic acid exerted chemo-preventive and therapeutic potential alone or in combination with Paclitaxel. Moreover, rosmarinic acid targets numerous signaling pathways associated with breast cancer.

Abstract
We managed to repurpose the old drug iodoquinol to a series of novel anticancer 7-iodo-quinoline-5,8-diones. Twelve compounds were identified as inhibitors of moderate to high potency on an inhouse MCF-7 cell line, of which 2 compounds (5 and 6) were capable of reducing NAD level in MCF-7 cells in concentrations equivalent to half of their IC50s, potentially due to NAD(P)H quinone oxidoreductase (NQO1) inhibition. The same 2 compounds (5 and 6) were capable of reducing p53 expression and increasing reactive oxygen species levels, which further supports the NQO-1 inhibitory activity. Furthermore, 4 compounds (compounds 5-7 and 10) were qualified by the Development Therapeutic Program (DTP) division of the National Cancer Institute (NCI) for full panel five-dose in vitro assay to determine their GI50 on the 60 cell lines. All five compounds showed broad spectrum sub-micromolar to single digit micromolar GI50 against a wide range of cell lines. Cell cycle analysis and dual staining assays with annexin V-FITC/propidium iodide on MCF-7 cells confirmed the capability of the most active compound (compound 5) to induce cell cycle arrest at Pre-G1 and G2/M phases as well as apoptosis. Both cell cycle arrest and apoptosis were affirmed at the molecular level by the ability of compound 5 to enhance the expression levels of caspase-3 and Bax together with suppressing that of CDK1 and Bcl-2. Additionally, an anti-angiogenic effect was evident with compound 5 as supported by the decreased expression of VEGF. Interesting binding modes within NQO-1 active site had been identified and confirmed by both molecular docking and dymanic experiments.

Abstract
Several studies have revealed that the combination of indomethacin, a nonsteroidal anti-inflammatory drug (NSAID), and vitamin D reduces the risk of common types of cancers. Nonetheless, research on the deal concentrations used to test the impact of vitamin D on colon cancer is deficient. Along these lines, the aim of the present study was to evaluate the possible role of indomethacin and vitamin D as a preventative as well as a therapeutic operator for colon cancer growth induced by dimethylhydrazine (DMH) in male Albino rats. Fifty male albino rats were utilized in this examination; five groups were assigned from the animals (10 animals each): i) control group considered healthy animals; ii) carcinogen group that received DMH only; iii) prophylactic group; iv) vitamin D and indomethacin-treated group; and v) 5-flurouracil (5-FU) group. Western blot technique was used to determine the expression of carcinoembryonic antigen (CEA) and platelet-derived growth factor (PDGF). Overexpression of CEA and PDGF was noted in the carcinogenic group, while expression of CEA and PDGF in the prophylactic, vitamin D and indomethacin and 5-FU groups were markedly reduced. There was a likewise decline in tissue caspase-3 activity and antioxidant parameters in the carcinogenic group, while, there was an increase in these markers in the 5-FU group as well as the prophylactic and vitamin D and indomethacin groups. The combination of vitamin D and indomethacin markedly reduced the incidence and severity of colon cancer. The molecular, biochemical and histopathological analysis related with the oral administration of vitamin D and indomethacin display its capacity to limit the frequency of colorectal cancer.

Abstract
Introduction: Achillea fragrantissima extract has been used in folk medicine as an anticancer. The present study describes the antitumor activities of the extract and the flavonoid compounds and attempts to explain the mechanisms underlying these activities. Methods: The whole plant of A. fragrantissima was collected and ground to produce a fine powder which subjected to the maceration process. Step gradient elution was used using silica gel vacuum liquid chromatography (VLC). The fractions were compared by thin layer chromatography (TLC) and concentrated. Final purification was performed using Sephadex LH-20 to give three compounds cirsiliol, chrysosplenol D and cirsimaritin from F4 and one compound, eupatilin-7-methyl ether from F6. In this study, Ehrlich’s ascites carcinoma (EAC) model was used as the model of cancer. Results: Achillea fragrantissima extract and its isolated methoxylated flavonoids significantly reduced the weight of tumor discs compared to EAC-control group. In addition, cirsimaritin and eupatilin 7-methyl ether treatments produced a dose-dependent reduction in tumor weight. Serum tumor necrosis factor-alpha (TNF-ɑ) level showed that A. fragrantissima extract and its isolated methoxylated flavonoid compounds significantly reduced its serum level compared to the EAC-control group. Furthermore, A. fragrantissima extract and the flavonoids significantly increased the Total antioxidant capacity (TAC) compared to EAC-control. A. fragrantissima extract and its isolated methoxylated flavonoids produced a better differentiation of tumor cells, with reduced nuclear pleomorphism and better formed tubular structures especially with high dose indicating the induction of apoptotic mechanism. Conclusion: Achillea fragrantissima extract and its isolated methoxylated flavonoids exhibit antitumor activities that may be attributed to the antioxidant properties and the induction of the apoptotic process.

Abstract
Introduction: Alzheimer’s disease (AD) is a neurodegenerative disorder that has no definite cure. Currently, there is great interest in using plant-based medicines to treat AD. In the present study, the neuroprotective effects of Astragalus kahiricus root extract were evaluated in a retrograde amnesia model. Methods: Male albino mice were given four training sessions in the Morris water maze for seven consecutive days. Treated groups were administered A. kahiricus (25 or 50 mg/kg, i.p.) before ethanol (3.5 gm/kg, i.p) injection. All animals were given a test session in the Morris water maze apparatus. Acetylcholinesterase activity and the levels of oxidative stress biomarkers were also measured. Results: Memory impairment was observed, after ethanol administration, as increased escape latency time and path length travelled by the animals. On the other hand, A. kahiricus significantly reduced both escape latency time and path length. In addition, the extract demonstrated an inhibitory effect on acetylcholinesterase activity and total nitrite level. Moreover, A. kahiricus significantly increased the level of reduced glutathione in mice brain. Conclusion: This study demonstrated the potential behavioural and biochemical neuroprotective properties of A. kahiricus root extract, which might further be considered an important candidate for the treatment of AD.

Abstract
OBJECTIVE The liver is an important organ that is actively involved in metabolic functions and targeted by a number of toxicants. Galectin-8 (Gal-8) is downregulated in liver fibrosis. Reduced Gal-8 expression correlates with inflammation and metastasis. Therefore, this study aimed to further investigate the benefits of combined administration of silymarin and ginger for CCl4-induced liver injuries in mice. We also investigated the mechanisms underlying the hepatoprotective activity of these herbal drugs and evaluated the role of Gal-8 and apoptosis in liver fibrosis. MATERIALS AND METHODS Eighty male albino mice were used in this study. Animals were divided into the following groups: control group, fibrotic group, silymarin and ginger group. The CCL4 model was used for the induction of liver fibrosis. RESULTS Gal-8 expression was reduced in the fibrotic group, while Gal-8 expression was increased in the ginger group and silymarin and ginger group. Tissue levels of nitric oxide (NO) and malondialdehyde (MDA) were markedly increased in the fibrotic group but decreased in the silymarin and ginger group. Additionally, tissue caspase-3 activity and antioxidant markers were decreased in the fibrotic group. However, these markers were increased in the silymarin and ginger group. CONCLUSIONS Gal-8 is a diagnostic and/or prognostic glycoprotein for liver fibrosis. The combination of silymarin and ginger has protective liver action and reduces the severity and incidence of liver fibrosis.

Abstract
Despite advances in cancer treatment, breast cancer remains one of the main life threatening diseases in women. Most anti-breast cancer drugs cause severe health complications and multidrug resistance. Although, some natural products, such as hesperidin (Hes), piperine (Pip) and bee venom (BV), showed anti-breast cancer effect when used separately, their combined effect together or with the anti-cancer drug tamoxifen (Tam) has not yet been studied. Herein, we hypothesized that these three natural products could potentiate the therapeutic effect of Tam when used together. First, we studied the cytotoxic effect of Hes, Pip, and BV on MCF7 and T47D cells using MTT assay and found reasonable IC50 comparable to that of Tam. Second, we checked the effect of all combinations (n = 67 for each cell line, prepared as non-constant ratio from fractions of IC50 of the four compounds) and found enhanced anti-proliferative effects on MCF7 and T47D and synergistic effect, revealed by combination index (CI) values below one. Next, the best 5 combinations with lowest Tam doses and CI but with highest cell death were selected for further molecular analysis in comparison to single-drug treatment. All single- and combined-treated groups showed a significant increase in apoptosis (indicated by upregulated mRNA level of the pro-apoptotic marker Bax and downregulated mRNA level of the anti-apoptotic marker Bcl2) and a significant decrease in mRNA level of the two breast cancer related receptors EGFR and ERα, with the best effect in combined groups especially that contained the 4 compounds, as compared to vehicle-treated group. Moreover, Pip, BV and all combinations, except Tam + Hes group, arrested MCF7 and T47D in G2/M phase of cell cycle, while Tam and/or Hes caused G0/G1 phase arrest. These results indicate that Hes, Pip and BV synergistically enhance the anti-cancer effect of Tam and could be used as safe adjuvant/vehicle to Tam in treatment of breast cancer after further confirmatory in vivo investigations.

Abstract
Local renin-angiotensin systems exist in various malignant tumor tissues; this suggests that the main effector peptide, angiotensin II, could act as a key factor in tumor growth. The underlying mechanisms for the anti-angiogenic effect of angiotensin II type 1 receptor blockers need to be further evaluated. The present study was carried out to investigate the anti-angiogenic effect of olmesartan alone or in combination with sorafenib, an angiotensin (1–7) agonist or an angiotensin (1–7) antagonist in Ehrlich's ascites carcinoma-bearing mice. The tumor was induced by intradermal injection of Ehrlich's ascites carcinoma cells into mice. Tumor discs were used to evaluate the microvessel density; the serum levels of vascular endothelial growth factor (VEGF) and serum insulin-like growth factor I (IGF-I); and their intratumoral receptors, VEGF receptor-2 and IGF-I receptor, respectively. All parameters were determined following the treatment course, which lasted for 21 days post-inoculation. Monotherapy with olmesartan and its combination with sorafenib resulted in a significant reduction in microvessel density and serum levels of VEGF and IGF-I, as well as their intratumoral receptors. In addition, the combination of olmesartan (30 mg/kg) with an angiotensin (1–7) agonist reduced the microvessel density, IGF-I serum levels and the levels of its intratumoral receptor. In conclusion, olmesartan reduced the levels of the angiogenesis markers IGF-I and VEGF and down-regulated the intratumoral expression of their receptors in a dose-dependent manner, and these effects were dependent on the angiotensin (1–7) receptor. These results suggest that olmesartan is a promising adjuvant to sorafenib in the treatment of cancer.
