Background:: Indole and pyrazoles are one of the prime structural units in the field of medicinal chemistry and have been reported to exhibit a variety of biological activities specifically anti-cancer. In view of their medicinal significance, we synthesized a conjugate of the two moieties to get access to newer and potential anti-cancer agents. Methods: Indolyl pyrazoles [3-(1,3-diphenyl-1H-pyrazol-4-yl)-2-(1-methyl-1H-indole-3-carbon yl)acrylonitriles] (4a-l) were synthesized by adopting simple and greener protocol and all the synthesized derivatives were docked against Bcl-2 protein and the selected chemical moieties were screened for their cytotoxicity by using the MTT assay. Results: : All the synthesized compounds were docked against BCL-2 protein in order to understand their binding pattern. Among the 12 compounds docked, 4d, 4f, 4h, 4j, and 4l compounds exhibited better protein binding interactions and the same were screened for their anti-cancer activity against A549 (lung) cancer cell lines at a concentration of 100 μM using Doxorubicin as standard. Substitutions such as N-benzyl, N-ethyl groups and halogen groups such as Br, Cl on indole ring showed moderate activity against A-549 cell lines. Conclusion:: Among the 5 indolyl pyrazole derivatives screened, compounds 4h and 4j showed significantly better activity with an IC50 of 33.12 and 34.24 μM, respectively. Further, structural tweaking of the synthesized new chemical entities may lead to potential hit/lead-like molecules.

Background: The role of microtubules in cell division and signaling, intercellular transport, and mitosis has been well known. Hence, they have been targeted for several anti-cancer drugs. Methods: A series of 3-(alkylthio)-5,6-diphenyl-1,2,4-triazines were prepared and evaluated for their cytotoxic activities in vitro against three human cancer cell lines; human colon carcinoma cells HT-29, human breast adenocarcinoma cell line MCF-7, human Caucasian gastric adenocarcinoma cell line AGS as well as fibroblast cell line NIH-3T3 by MTT assay. Docking simulation was performed to insert these compounds into the crystal structure of tubulin at the colchicine binding site to determine a probable binding model. Compound 5d as the most active compound was selected for studying of microtubule disruption. Results: Compound 5d showed potent cytotoxic activity against all cell lines. The molecular modeling study revealed that some derivatives of triazine strongly bind to colchicine binding site. The tubulin polymerization assay kit showed that the cytotoxic activity of 5d may be related to inhibition of tubulin polymerization. Conclusion: The cytotoxicity and molecular modeling study of the synthesized compounds with their inhibition activity in tubulin polymerization demonstrate the potential of triazine derivatives for development of new anti-cancer agents.

Background: Berberine (BBR), an isoquinoline plant alkaloid isolated from plants such as Coptis chinensis and Hydrastis canadensis, own multiple pharmacological activities. Objective: In this study, seven BBR derivatives were synthesized and their anticancer activity against HeLa cervical and A549 human lung cancer cell lines were evaluated in vitro. Methods: The anti-cancer activity was measured by MTT assay, and apoptosis was demonstrated by the annexin V-FITC/PI staining assay. The intracellular oxidative stress was investigated through DCFH-DA assay. The molecular docking study was carried out in molecular operating environment (MOE). Results: Compound B3 and B5 showed enhanced anti-cancer activity compared with BBR, the IC50 for compound B3 and B5 were significantly lower than BBR, and compound B3 at the concentration of 64 or 128 µM induced apoptosis in HeLa and A549 cell lines. The reactive oxygen species (ROS) was generated in both cell lines when treated with 100 µM of all the compounds, and compound B3 and B5 induced higher activity in the generation of ROS, while compound B3 exhibited the highest activity, these results are in accordance with the cytotoxicity results, indicating the cytotoxicity were mostly generated from the oxidative stress. In addition, molecular docking analysis showed that compound B3 had the greatest affinity with Hsp90. Upon binding, the protective function of Hsp90 was lost, which might explain its higher cytotoxicity from molecular interaction aspect. Conclusion: All the results demonstrated that compound B3 and B5 showed significantly higher anti-cancer ability than BBR, and compound B3 is a promising anticancer drug candidate.

Znfe2o4 Nanoparticles

Background: The growing unsatisfaction toward the available traditional chemotherapeutic agents enhanced the need to develop new methods for obtaining materials with more effective and safe anti-cancer properties. Over the past few years, usage of metallic nanoparticles has been a target for researchers of different scientific and commercial fields due to their tiny sizes, environment friendly properties and wide range applications. To overcome the obstacles of traditional physical and chemical methods for synthesis of such nanoparticles, a new less expensive and eco-friendly method has been adopted using natural existing organisms as a reducing agent to mediate synthesis of the desired metallic nanoparticles from their precursors, a process called green biosynthesis of nanoparticles. Objective: Here in the present study, zinc iron bimetallic nanoparticles (ZnFe2O4) were synthesized via an aqueous extract of Boswellia Carteri resin mixed with zinc acetate and iron chloride precursors, and they were tested for their anticancer activity. Methods: Various analytic methods were applied for the characterization of the Phyto synthesized ZnFe2O4 and they were tested for their anticancer activity against MDA-MB-231, K562, MCF-7 cancer cell lines and normal fibroblasts. Results: Our results demonstrate the synthesis of cubic structured bimetallic nanoparticles ZnFe2O4 with an average diameter 10.54 nm. MTT cytotoxicity assay demonstrate that our phyto-synthesized ZnFe2O4 nanoparticles exhibited a selective and potent anticancer activity against K562 and MDA-MB-231 cell lines with IC50 values 4.53 µM and 4.19 µM, respectively. Conclusion: In conclusion, our bio synthesized ZnFe2O4 nano particles show a promising environmentally friendly of low coast chemotherapeutic approach against selective cancers with a predicted low adverse side effect toward normal cells. Further in vivo advanced animal research should be done to execute their applicability in living organisms.

Background: Targeting evolutionarily conserved proteins in malignant cells and the adapter proteins involved in signalling that generates from such proteins may play a cardinal role in the selection of anti-cancer drugs. Drugs targeting these proteins could be of importance in developing anti-cancer drugs. Objectives: We inferred that drugs like loperamide and promethazine that act as antagonists of proteins conserved in cancer cells like voltage-gated Calcium channels (Cav), Calmodulin (CaM) and drug efflux (ABCB1) pump may have the potential to be re-purposed as an anti-cancer agent in Prostate Cancer (PCa). Methods: Growth and cytotoxic assays were performed by selecting loperamide and promethazine to target Cav, CaM and drug efflux (ABCB1) pumps to elucidate their effects on androgen-independent PC3 and DU145 PCa cell lines. Results: We show that loperamide and promethazine in doses of 80-100μg/ml exert oncocidal effects when tested in DU145 and PC3 cell lines. Diphenhydramine, which shares its targets with promethazine, except the CaM, failed to exhibit oncocidal effects. Conclusion: Anti-cancer effects can be of significance if structural analogues of loperamide and promethazine that specifically target Cav, CaM and ABCB1 drug efflux pumps can be synthesized, or these two drugs could be re-purposed after human trials in PCa.
