Abstract Background: A series of aryl-piperazine derivatives of 1,7,8,9-tetrachloro-10,10-dimethoxy-4-azatricyclo [5.2.1.02,6] dec-8-ene-3,5-dione were synthesized. The chemical structures of the desired compounds were identified by 1H NMR, ESI-MS and elementary analytical. The anti-cancer and anti-angiogenesis activities of the newly synthesized compounds were evaluated by proliferation and migration assays, respectively. Results: The screening results demonstrated that compounds 2 and 5 showed potent anti-tumor activity (IC50 values ranging from 7.1 to 15.9μM) with low cytotoxic activities (IC50＞79.3μM). Although compound 5 showed little effects on endothelia proliferation (IC50=65.3μM), it indeed significantly abrogated endothelia cell migration (IC50=6.7μM). Conclusions: This work may impart new direction for the investigations of aryl-piperazine derivatives and lead to the development of potent novel anti-tumor and anti-angiogenesis agents.

Synthesis And Biological Evaluation

Two benzimidazole derivatives namely 2-methyl-1H-benzimidazole (1) and 1H-benzimidazol-2- ylmethanol (2) were synthesized in high yields by condensing O-phenylenediamine with two different carboxylic acid derivatives: glacial acetic acid and glycolic acid, following a different synthetic protocol. Structures were elucidated by spectroscopic methods. Among the two benzimidazole derivatives synthesized, 2-methyl-1Hbenzimidazole (1) showed moderate antioxidant activity with IC50 values of 144.84?g/ml whereas 1H-benzimidazol- 2-ylmethanol (2) displayed mild antioxidant activity (IC50 value 400.42 ?g/ml). Compound 1 also exhibited prominent cytotoxic activities with the LC50 value of 0.42 ?g/ml when compared to the standard vincristine sulphate (LC50 value of 0.544 ?g/ ml). It also demonstrated weak antimicrobial activity having 7-8 mm of zone of inhibition.Dhaka Univ. J. Pharm. Sci. 15(1): 83-87, 2016 (June)

: Esterified and alkyl amine derivatives of mangiferin were synthesized and evaluated for in vitro antioxidant and anticancer activities. The chemical structures of the derivatives were confirmed using elemental analysis and spectral data.The antioxidant activity was assessed using 2,2-diphenyl-1-picrylhydrazy (DPHH) assay and some derivatives displayed antioxidant activity better than mangiferin and standard drug ascorbic acid. Among the synthesized derivatives, few exhibited enhanced anticancer activity against human breast (MDA-MB-231) cancer cell lines, then the parent mangiferin.
