Journal ArticleDOI

Synthesis of novel thiazolone-based compounds containing pyrazoline moiety and evaluation of their anticancer activity.

TL;DR: The most efficient anticancer compound 16 was found to be active with selective influence on colon cancer cell lines, especially on HT 29 (logGI(50)=-6.37) and in vitro anticancer activity of synthesized compounds were tested by the National Cancer Institute.
Journal ArticleDOI

Synthesis and anticancer activity evaluation of 4-thiazolidinones containing benzothiazole moiety

TL;DR: In vitro anticancer activity of the synthesized compounds was tested by the National Cancer Institute and two of them has revealed the antic cancer activity on leukemia, melanoma, lung, colon, CNS, ovarian, renal, prostate and breast cancers cell lines.
Journal ArticleDOI

Synthesis of new 4-thiazolidinone-, pyrazoline-, and isatin-based conjugates with promising antitumor activity.

TL;DR: The most effective anticancer compound 10 was found to be active with mean GI₅₀ and TGI values of 0.071 μM and 0.76 μM, respectively and demonstrated the highest antiproliferative influence on the non-small-cell lung cancer cell line HOP-92.
Journal ArticleDOI

Synthesis and Anticancer Activity of Isatin-Based Pyrazolines and Thiazolidines Conjugates

TL;DR: Five novel isatin based conjugates with thiazolidine and pyrazoline moieties were synthesized and found to be the most active candidate with selective influence on leukemia subpanel tumor cell lines with GI50 values range of 0.69–3.35 µM.
Journal ArticleDOI

Synthesis of 5-arylidene-2-amino-4-azolones and evaluation of their anticancer activity.

TL;DR: Series of novel 5-arylidene-2-arylaminothiazol-4(5H)-ones and 2-aryl(benzyl)amino-1H-imidazol- 4(5h)-ones were synthesized from appropriate 2-alkylthioazols using nucleophilic substitution in position 2 by various anilines and benzylamines and Knoevenagel reaction to disclose probable modes of anticancer action.
