  Synthesis of some new 2-amino-6-thiocyanato benzothiazole derivatives bearing 2,4-thiazolidinediones and screening of their in vitro antimicrobial, antitubercular and antiviral activities

  摘要：

  A series of new (E)-2-(5-substituted benzylidene-2,4-dioxothiazolidin-3-yl)-N-(6-thiocyanatobenzo[d]thiazol-2-yl)acetamides have been synthesized. The structures of title compounds have been confirmed by elemental analyses, IR, H-1 NMR and C-13 NMR spectral data. All the synthesized compounds were tested for antimicrobial and antitubercular activity and also were evaluated for anti-HIV activity. Several compounds exhibited good antibacterial activity (9, 15, 27 and 31 against E. coli; 8 and 28 against S. aureus); some displayed good antifungal activity (4, 7, 13, 19, 23, 24, 25 and 31 against C. albicans). Compounds 14, 20 and 22 showed good antitubercular activity. Unfortunately, none of the compounds were found to be active against anti-HIV-1. However, one of the intermediates, the 2-chloro-N-(6-thiocyanatobenzo[d]thiazol-2-yl)acetamide, showed significant cytotoxicity for MT-4 cells (CC50 = 8.0 A mu M).

  Tetrabutylammonium bromide and K₂CO₃: an eco-benign catalyst for the synthesis of 5-arylidene-1,3-thiazolidine- 2,4-diones via Knoevenagel condensation

  摘要：

  Phase-transfer catalyzed, energy-efficient and facile synthesis of 5-arylidene-1,3-thiazolidine-2,4-diones was developed. Three independent variables (temperature, bases and phase-transfer catalyst (PTC)) were screened through one-factor-at-a time (OFAT) study. The optimum reaction conditions suggested by the OFAT analysis were the use of tetrabutylammonium bromide (8 mol%) and potassium carbonate (1 mmol) for the reaction at 100 degrees C. The nitrogen of PTC stabilizes carbonyl groups of thiazolidine-2,4-dione (TZD). The active methylene hydrogen of TZD forms potassium salt with potassium carbonate and generates 5-arylidene-1,3-thiazolidine-2,4-diones (1-16) through nucleophilic attack on the carbonyl carbon of arylaldehydes. The prominent advantages of this new process are economic viability, shorter reaction time (15 min), simple product isolation (non-chromatographic method), good to excellent yields (78-96%) and solvent-free conditions.
