A series of Rhodanine derivatives were synthesized by Knoevenagel condensation. All the synthesized compounds were tested for their in vitro anticancer activity against MCF-7 and BT-474 human breast cancer cell lines. All the synthesized compounds were characterized and screened for their antimicrobial activity against the bacterial and fungal strain. Majority of the compounds showed good to moderate anticancer and antimicrobial activity. Among these compounds, one showed promising activity against gram-positive bacteria B. subtilis and S. aureus when compared with ampicillin. Some of the most potent compounds possessed selective antimicrobial activity.

“…15 Some benzthiazole forms key building block of some of the biologically active derivatives. [16][17] By considering the diversified biological activity of benzo [d]thiazol and continuation of our research work, [18][19][20] we have synthesized a series of substitutedbenzo [d]thiazole derivatives and all the synthesized compounds were tested for their biological activity in cell line and enzymatic study.…”

A series of novel derivatives containing N 4-(4-fluorophenyl)-N 2-substitured-benzo[d]thiazole-2,4-dicarboxamides were synthesized via an efficient, mild and convenient multistep reaction protocol with excellent yields. The structure of the synthesize compounds were confirmed by IR, 1 H NMR, 13 C NMR, 19 F NMR, mass spectra, elemental analysis and purity was checked by HPLC. All synthesized compounds were screened for anticancer activity against A-549 and Du-145 cancer cell lines by MTT assay. The preliminary bioassay suggests that most of the compounds show anti-proliferation with different degrees. The synthesized compound shows IC50 values in the range of 1.52-17.18 µM in both cell lines. The compounds having electron donating groups had higher anticancer activity compared compounds with electron withdrawing substitutions.

“…32,33 Ultrasonic irradiation has been acknowledged as an innocuous, green technique and its application today has been a boon in serving a new pathway for several chemical processes like reagent activation in the synthesis of organic and inorganic compounds. 34 In view of the above considerations and in continuation of our previous work on thiazoles, thiazolidinones and sulphonamide derivatives of pharmaceutical interest, [35][36][37][38][39][40][41][42][43][44][45][46][47] we wish to report a simple, mild, competent and environmentally benign method for the synthesis and characterization of novel rhodanine derivatives 3, 4 and 6a-l by ultrasound irradiation and conventional technique via potassium carbonate catalyzed in water media.…”

An environmentally benign aqueous protocol for the synthesis of novel 2-((5-(4methoxybenzylidene)-4-oxo-4,5-dihydrothiazol-2-yl)amino)substituted acid by using potassium carbonate as a base has been achieved. These ultrasound irradiation and conventional technique reaction proceed efficiently in water in the absence of organic solvent. In comparison with conventional methods, our protocol is convenient and offers several advantages, such as shorter reaction time, higher yields, milder conditions and environmental friendliness.
