Abstract
Background and the purpose of the study There has been increscent interest in the field of cancer chemotherapy by discovery and development of novel agents with high efficacy, low toxicity, and minimum side effects. In order to find new anticancer agents, we replaced the pyrazolone part of well-known cytotoxic agent SJ-172550 with 7-methoxychroman-4-one. Thus, a novel series of 3-benzylidene-4-chromanones were synthesized and tested in vitro against human cancer cell lines. Methods The title compounds were prepared by condensation of 7-methoxychroman-4-one with suitable aldehydes in appropriate alcohol in the presence of gaseous HCl. The antiproliferative activity of target compounds were evaluated against MDA-MB-231 (breast cancer), KB (nasopharyngeal epidermoid carcinoma) and SK-N-MC (human neuroblastoma) cell lines using MTT assay. Results Although the direct analog of SJ-172550 (compound 5d) did not show any cytotoxic activity against tested cell lines, but 2-(2-chloro-6-methoxyphenoxy)acetic acid methyl ester analog 5c showed some activity against MDA-MB-231 and SK-N-MC cells. Further modification of compound 5c resulted in the 3-chloro-4,5-dimethoxybenzylidene derivative 5b which demonstrated better cytotoxic profile against all tested cell lines (IC50 values = 7.56–25.04 μg/ml). Conclusion The results demonstrated that the cytotoxic activity of compound 5b against MDA-MB-231 and SK-N-MC cells is more than etoposide. Therefore, compound 5b prototype could be considered as novel cytotoxic agent for further developing new anticancer chemotherapeutics.

Abstract
A series of 4-hydroxycoumarin derivatives were designed and synthesized as new acetylcholinesterase (AChE) inhibitors which could be considered for Alzheimer's disease therapeutics. Among the 19 coumarin-derived compounds tested toward Electrophorus electricus acetylcholinesterase (eelAChE) and horse serum butyrylcholinesterase (eqBChE), N-(1-benzylpiperidin-4-yl)acetamide derivative 4m displayed highest AChE inhibitory activity (IC50 = 1.2 μM) and good selectivity (37 times). The docking study of the most potent compound 4m, indicated that Phe330 is responsible for ligand recognition and trafficking by forming π-cation interaction with benzylpiperidine moiety. Furthermore, the formation of an additional π-π interaction between coumarin moiety and Trp279 of peripheral anionic site could stabilize the ligand in the active site resulting in more potent inhibition of the enzyme.

Abstract
Flower of Rosa damascena Mill is widely used in Iran for gastrointestinal (GI) disorders. However, its pharmacological action on ileum contraction has not been studied. In this research we have investigated ileum motility effect of essential oil of flower petals of R. damascena growing in Kashan, Iran, and two of its constituents. The essential oils obtained by hydrodistillation were investigated by a combination of GC and GC/MS. More than 34 compounds have been identified. The main constituents of the essential oil were β-citronellol (23%), nonadecane (16%), geraniol (16%) and heneicosane (5%). A portion of rat isolated ileum was suspended under 1g tension in Tyrode's solution at 37°C and gassed with O2. Effect of the R. damascena essential oil (2.5-160 μg/ml), geraniol (0.2-3.2 μg/ml) and citronellol (0.8-6.4 μg/ml) were studied on ileum contractions induced by KCl, acetylcholine (ACh) and electrical field stimulation (EFS) and compared with standard drugs atropine and loperamide. The contractile response of EFS was mediated mainly through the intramural nerve plexuses, because its response was inhibited by loperamide and partially reduced by atropine. The essential oil concentration dependently inhibited the response to KCl (IC50=67 ± 8.4μg/ml) and EFS (IC50=47 ± 10.6 μg/ml). Geraniol (IC50=1.7 ± 0.15 μg/ml for KCl) and citronellol (IC50=2.9 ± 0.3 μg/ml for KCl) also had inhibitory effect of ileum contraction and both were more potent than the essential oil. It was concluded that R. damascena essential oil mainly had an inhibitory effect on ileum contractions and geraniol and citronellol had a major role in inhibitory effect of the essential.

Abstract
Rosa damascena flower is widely used for gastrointestinal (GI) disorders. However, its pharmacological action on isolated ileum has not been studied. In this research, the effect of extract of flower petals of R. damascena Mill. growing in Kashan, Iran, on ileum motility was investigated. Hydroalcoholic extract was prepared by percolation method. A section of rat ileum was suspended in an organ bath containing Tyrode's solution. The tissue was stimulated with electrical field stimulation (EFS), KCl and acetylcholine (ACh). The tissue was kept under 1g tension at 37°C and continuously gassed with O2. Effect of the R. damascena extract was studied on ileum contractions induced by EFS, KCl and ACh and compared with that of atropine. R. damascena extract (10-100 mg/ml) induced a contraction in rat isolated ileum while at 1mg bath concentration it had relaxant effect on rat ileum. Hydroalcoholic extract of R. damascena (1-8 mg/ml) concentration dependently inhibited ileum contraction induced by KCl (IC50=3.3 ± 0.9 mg/ml), ACh (IC50=1.4 ± 0.1 mg/ml) and EFS (IC50=1.5 ± 0.3 mg/ml). The vehicle had no significant effect on ileum contractions. From this experiment it was concluded that R. damascena extract at microgram concentrations had stimulatory effect on ileum smooth muscle. However, at milligram concentrations, it shows an inhibitory effect. This is most likely due to presence of different components in the extract. The stimulatory effect of the extract confirms its benefits for the treatment of constipation. Therefore, separation and identification of active components is recommended.

Abstract
A series of 2-amino-4-(nitroalkyl)-4H-chromene-3-carbonitriles were synthesized by an efficient multicomponent reaction in aqueous media using DBU as a catalyst at room temperature. Mild condition, environment friendly procedure and excellent yields are the main advantages of this procedure. The cytotoxic activity of target compounds were evaluated against three cancer cell lines MDA-MB-231, MCF-7 and T47D in comparison with etoposide as reference drug. Generally, all compounds showed good cell growth inhibitory activity with IC(50) values less than 30 μg/mL. Their activities were comparable or more potent than standard drug etoposide. The 6-bromo- derivatives 7e and 7f showed promising cytotoxic activity with IC50 values in the range of 3.46-18.76 μg/mL, being more potent than etoposide against all tested cell lines.

Abstract
CONTEXT As microtubules are highly involved in cellular growth, it appears to be a preferential target for cancer treatment. Therefore, many efforts have been performed to discover drugs that affect on microtubule function. Several microtubule inhibitors are in various stages of laboratory evaluations and clinical trials. OBJECTIVE A series of chromene-based chalcones with chlorine, methoxy, fluorine, tetrahydropyranyloxy and cyanide substituents were prepared and evaluated for cytotoxic effects against K562 and SK-N-MC cell lines, and the inhibitory effect on tubulin polymerization was studied as well. MATERIALS AND METHODS MTT, tubulin polymerization assays and binding measurements were evaluated by using related spectroscopy. Immunocytochemical study, morphological observations and apoptosis assay were examined using a fluorescence microscope and a flow cytometer. RESULTS (E)-3-(6-Chloro-2H-chromen-3-yl)-1-(3,4,5-trimethoxyphenyl) prop-2-en-1-one (compound 14) proved to be the most active in this series as an inhibitor of tubulin assembly [IC₅₀, 19.6 µM] and cytotoxic agent on K562 cells [IC₅₀, 38.7 µM]. Furthermore, these compounds exhibited a strong inhibitory effect on tubulin polymerization and reduced the in vitro assembly and bundling of proto-filaments. Also, compound 14 bound to the tubulin with a dissociation constant of 9.4 ± 0.7 µM and induced conformational changes in this protein. DISCUSSION AND CONCLUSION This study suggests that the compound 14 could be a good antitumor agent because of its biological functions. Compound 14 appears to bind directly to tubulin and thereby perturbs microtubule stability and the function of the spindle apparatus, which causes cancer cells to arrest and undergo apoptosis.

Abstract
A series of halogenated flavanones were synthesized from 2-hydroxychalcones and tested for their cytotoxicity against a panel of human cancer cell lines. Among the synthesized compounds, 3',7-dichloroflavanone (2d) showed the highest activity against MCF-7, LNCaP, PC3, Hep-G2, KB and SK-N-MC cells. However, 3',6-dichloroflavanone (2g) with IC(50) value of 2.9 ± 0.9 μM was the most potent compound against MDA-MB-231 cells, being approximately 12 times more active than etoposide as reference drug. According to the flow-cytometric analysis, compound 2g can induce apoptosis by 66.19 and 21.37% in PC3 and MDA-MB-231 cells, respectively. The results of acridine orange/ethidium bromide staining and TUNEL assay suggested that the cytotoxic activity of this compound in PC3 and MDA-MB-231 cells occurs via apoptosis.

Abstract
Background The currently available antifungal drugs suffer from toxicity, greatest potential drug interactions with other drugs, insufficient pharmacokinetics properties, and development of resistance. Thus, development of new antifungal agents with optimum pharmacokinetics and less toxicity is urgent task. In the search for new azole antifungals, we have been previously described azolylchromanone oxime ethers as rigid analogs of oxiconazole. In continuation of our work, we incorporated phenylhydrazone moiety instead of oxime ether fragment in azolylchromanone derivatives. Methods The 3-azolyl-4-chromanone phenylhydrazones were synthesized via ring closure of 2-azolyl-2'-hydroxyacetophenones and subsequent reaction with phenylhydrazine. The biological activity of title compounds was evaluated against different pathogenic fungi including Candida albicans, Saccharomyces cerevisiae, Aspergillus niger, and Microsporum gypseum. Docking study, in silico toxicity risks and drug-likeness predictions were used to better define of title compounds as antifungal agents. Results The in vitro antifungal activity of compounds based on MIC values revealed that all compounds showed good antifungal activity against C. albicans, S. cerevisiae and M. gypseum at concentrations less than 16 μg/mL. Among the test compounds, 2-methyl-3-imidazolyl derivative 3b showed the highest values of drug-likeness and drug-score. Conclusion The 3-azolyl-4-chromanone phenylhydrazones considered as analogs of 3-azolyl-4-chromanone oxime ethers basically designed as antifungal agents. The antifungal activity of title compounds was comparable to that of standard drug fluconazole. The drug-likeness data of synthesized compounds make them promising leads for future development of antifungal agents.

Abstract
Background and the purpose of the study Piperazinyl quinolones such as ciprofloxacin, ofloxacin and levofloxacin are an important group of quinolone antimicrobials which are widely used in the treatment of various infectious diseases. In the present study, we synthesized a new series of levofloxacin derivatives and evaluated their antibacterial activities. Methods The N-substituted analogs of levofloxacin 6a–j were prepared by nucleophilic reaction of N-desmethyl levofloxacin 11 with thienylethyl bromide derivatives 8 or 9. All target compounds were tested using conventional agar dilution method in comparison to levofloxacin and N-desmethyl levofloxacin and their MIC values were determined against a panel of Gram-positive and Gram-negative bacteria. Results All compounds showed significant antibacterial activities against Gram-positive bacteria (MIC = 0.04-6.25 μg/mL); however, the activity against Gram-negative bacteria was lower (MIC = 1.56–100 μg/mL). As is evident from the data, oxime derivatives 6e, 6h and 6i are superior in inhibiting the growth of Gram-positive bacteria (MIC = 0.04–0.19 μg/mL), and their activities were found to be 5–25 times better than N-desmethyl levofloxacin 11 and equal or better than levofloxacin 4. Conclusion We have designed and synthesized novel quinolone derivatives bearing functionalized thienylethyl moiety on the piperazine ring of levofloxacin. The results of antibacterial screening against Gram-positive and Gram-negative bacteria revealed that the introduction of functionalized thienylethyl moiety on the piperazine ring of levofloxacin can improve the activity against Gram-positive bacteria. Gram-positive bacteria are responsible for a wide range of infectious diseases, and rising resistance in this group is causing increasing concern. Thus, this study introduces structural features of levofloxacin scaffold for development of new candidates in the field of anti-Gram positive chemotherapy

Abstract
Background. Multiple sclerosis (MS) is an autoimmune inflammatory disease of central nervous system (CNS). MS affects quality of Life (QOL) due to physical disability and other associated problems. Disease-modifying agents like interferon beta (IFNB) have been widely utilized in this patient population; however, their frequency, route of administration, side effects, high cost, and also the question of whether they are truly beneficial for longer-term outcomes and QOL need to be further investigated. Objectives. To assess QOL in patients with multiple sclerosis receiving interferon beta-1a (Avonex or CinnoVex) and in order to compare QOL in groups receiving Avonex and CinnoVex, respectively, also, to evaluate whether the more cost-effective biosimilar form of IFNB (CinnoVex) has the same effect on QOL and can be substituted for Avonex. Methods. We conducted a 30-month, nonrandomized longitudinal study and recruited a total of 92 patients diagnosed with relapsing-remitting MS. The patients were distributed in Avonex and CinnoVex groups with 46 patients in each group. Quality of life was assessed by means of MSQOL-54 questionnaire, four times a year, at baseline and at months 4, 8, and 12 of the study. Results. Mean age ± SD was 30.5 ± 8.9 and 32.3 ± 9.0 years in Avonex and CinnoVex groups, respectively, and P value of gender was different (P value : 0.036). The physical health composite scores were 61.8 and 59.8 (P values 0.677 and 0.884) for Avonex and CinnoVex groups, in that order. The results of the study revealed no significant difference between the two groups with regard to physical health, health perception, energy, and role limitations due to physical problems, pain, sexual and social function, and physical health distress scores. Further, interferon therapy did not significantly impact patients' QOL after a year of treatment with either Avonex or CinnoVex. Conclusions. According to the present study, treatment with IFNB (Avonex or CinnoVex) did not affect QOL during a year of therapy. Further studies with longer follow-up periods are required to assess the value of interferons on long-term outcomes and patient's QOL.

Abstract
A novel series of 5-(5-nitrofuran-2-yl)-1,3,4-thiadiazol-2-amines were synthesized by introducing N-[(1-benzyl-1H-1,2,3-triazol-4-yl)methyl] moiety as a new functionality on the C-2 amine of thiadiazole ring via click chemistry. The title compounds namely, N-[(1-benzyl-1H-1,2,3-triazol-4-yl)methyl]-5-(5-nitrofuran-2-yl)-1,3,4-thiadiazol-2-amines (3a-n) were characterized by IR, NMR and MS spectra. These compounds were evaluated for their in vitro anti-leishmanial activity against promostigote form of the Leishmania major. Most compounds exhibited good anti-leishmanial activity against the promastigote form of L. major. The most active compound against promostigotes was found to be 4-methylbenzyl analog 3i, which significantly decreases the number of intracellular amastigotes per macrophage, percentage of macrophage infectivity and infectivity index.
