Aims and Objective: A series of novel phthalazine derivatives was synthesized with versatile, readily accessible electrophilic and nucleophilic reagents. The newly synthesized compounds were confirmed by the results of spectroscopic measurements. Hence, their potential clinical application investigated in particular for cancer treatment. Materials and Methods: The newly synthesized compounds were characterized by spectroscopic measurements and were tested for their in vitro anticancer activity by MTT assay against human liver cancer cell line. Docking study of all the synthesized compounds was performed within the active site of the enzyme VEGFR-2 (Vascular Endothelial Growth Factor Receptor-2). Results: The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 µM. Docking study showed that the synthesized compounds were fit in the VEGFR-2 active site almost at the same position of sorafenib and vatalanib with comparable docking scores (-15.20 to -8.92 was kcal/mol). Conclusion: we have synthesized a novel series of phthalazine derivatives and evaluated their potential anticancer activity against HEPG2 cell line. The quinazoline derivative 12 emerged as the most potent compound in this study with an IC50 value of 5.4 µM. The SAR and docking studies pointed out that rigidification of the structure resulted in better activity and better binding within the active site of VEGFR-2 as in compounds 3, 5, 6 and 12. These results introduced new phthalazine derivatives having promising activity which could lead to the development of more potent anticancer agents.

Inhibition Of Proliferation

Phycocyanin from Spirulina platensis extract has anticancer activity against various types of cancer cell cultures. However study about its effect on colon cancer cell lines, especially the WiDr, has not been reported before. This study aimed to reveal the anticancer activity of phycocyanin from Spirulina platensis extract on WiDr cells. The research was an in vitro experimental study, with the investigation on cytotoxicity also antiproliferation as the anticancer parameters. Both cytotoxicity and antiproliferation test was conducted through MTT assay to observe the visualization and inhibition of proliferation of different concentrations of phycocyanin in several incubation times on the WiDr colon cancer cell line. The obtained data were then processed statistically with the Two Way ANOVA test at a significance value of p <0.05 and followed with the Post Hoc test since there were significant differences. Based on the results, it could be postulated that phycocyanin extracted from freshwater Spirulina platensis was classified as non-toxic (IC50 of 855 µg/ml). Consequently, it is less potential to be used as the treatment for colon cancer. However, phycocyanin could inhibit the proliferation of the WiDr cell for approximately 47.4%, specifically at the concentration of 1710 µg/ml for 72 hours. It could be concluded that freshwater phycocyanin is less effective as an anticancer substance. The benefit of this study is to provide the new scientific evidence of the contrary results of freshwater phycocyanin activity from Spirulina platensis as an anticancer agent of colon cancer.

A series of several diazenyl Schiff base derivatives were designed and synthesized through azo coupling of diazotised primary amines with the novel synthesized Schiff base ligand (E)-N-((2-chloroquinolin-3-yl) methylene)-4-phenylthiazol-2-amine. All the synthesized compounds have been analysed by different spectral techniques such as elemental analysis, 1H NMR, FT-IR, UV-Vis and LC-MS for their structural confirmation. The above conjugates have been studied for their solvent effects by treating them with different solvents. The results of in vitro cytotoxic study of the synthesized compounds against MCF 7 (human breast cancer cell line) and K562 (Chronic Myeloid Leukemia cell line) revealed that some of the compounds show cytotoxic effect. However, the compounds (NZ)-N-(((4-bromo-3-methylphenyl) diazenyl) (2-chloroquinolin-3-yl) methylene)-4-phenylthiazol-2-amine: (5d) and 4-(((Z)-(2-chloroquinolin-3- yl)(4-phenylthiazol-2-ylimino)methyl)diazenyl)phenol (5e) showed potent cytotoxic activity in comparison to other compounds against MCF 7. Corroborating the results of anticancer activity, it is found to be observed that the compound 4- (((Z)- (2-chloroquinolin-3-yl) (4-phenylthiazol-2-ylimino)methyl) diazenyl) phenol (5e) showed excellent anticancer activity against MCF 7, which is further justified by the apoptosis study through Annexin V-FITC/PI analysis.
