2, 3(Department of Chemistry, College of Education / University of Tikrit, Tikrit, Iraq) Abstract: This research, involved synthesis of a series of new compound containing different derivatives. The synthesis involved treatment of 6- methyl 2-thiouracil with chloroacetyl chloride to give 1- chloroacetyl 6-File Size: 1MB. carbothiaote derivatives were synthesized. Substituted 2-phenyl-benzothiazole were synthesised by condensing substituted benzoic acid with 2-amino thiophenol in the presence of phosphoric acid and 3-benzothiazoleylsubstituted carbothiaote derivatives were prepared by condensing 2-mercaptobenzothiazole with substituted acid Size: KB.

Cancer. 2-Methoxyestradiol (2-MeOE2) 1, an endogenous estrogen metabolite, has emerged as a promising therapeutic candidate for the treatment of a number of conditions. The discovery that 2-MeOE2 inhibits angiogenesis, is anti-proliferative and has in vivo anti-tumour activity 1 has led to its evaluation in phase I/II clinical trials against a range of cancers under the trade name Panzem™.Cited by: Competition assays indicated that bile acids played an important role to carry the derivatives into the bile acid-positive cancer cells.
The results suggest that the introduction of bile acids in the 20th position of camptothecin promote the anti-tumour targeting activity of these derivatives to liver cancer cells. Competition assays indicated that bile acids played an important role to carry the derivatives into the bile acid-positive cancer cells.
The results suggest that the introduction of bile acids in the 20th position of camptothecin promote the anti-tumour targeting activity of these derivatives to liver cancer by: 6. Twenty-nine novel indole-chalcone derivatives were synthesized and evaluated for antiproliferative activity.
Among them, 14k exhibited most potent activity, with IC50 values of 3–9 nM against six cancer cells, which displayed a –fold increase in activity when compare with compound 2.
Further investigation revealed 14k was a novel tubulin polymerization inhibitor binding to the Cited by: derivatives containing various amino groups at position 2, 4 or 6 have been known as anticancer drugs (Sączewski et al., ).
