Schiff bases were obtained by condensation of 2-amino-l,3,4-thiadiazole with 5-substituted-salicylaldehydes which were further used to obtain complexes of the type [M(L)(2)]Cl(2), where M=Co(II), Cu(II), Ni(II) or Zn(II). The new compounds described here have been characterized by physical, spectral and analytical data, and have been screened for antibacterial activity against several bacterial...
Isonicotinamide (INAM), 6-aminopicolinamide, and several related nicotinamide analogs have been demonstrated to enhance the activity of 2-arnino-l,3,4-thiadiazole (ATDA) against transplanted mouse leukemias. The combinations were effective only against those leukemias which also responded to ATDA alone. The potentiation of therapeutic effect was paralleled by potentiation of the degree of host ...
New series of 1,3,4-thiadiazoles have been prepared via reaction of 1,3,4-thiadiazolenaminones 1 with N-phenyl 2-oxopropanehydrazonoyl chloride (2) in dioxane in the presence of triethylamine. Also, some new heterocycles incorporating 1,3,4-thiadiazole ring were obtained by reaction of 1,3,4-thiadiazolenaminones 1 with nitrogen-nucleophiles like hydrazine hydrate, 3-amino-1,2,4-triazole and ...
Cross-linked polymer dots with intense and narrow yellow emission were designed using boron-dipyrromethene (BODIPY) polymer as the acceptor and poly[9,9-dioctylfluorenyl-2,7-diyl-co-1,4-benzo-{2,1'-3}-thiadiazole] (PFBT) polymer as the donor. The emission fwhm's of the polymer dots (Pdots) were 37 nm. CL-BODIPY 565 Pdots were about 5 times brighter than commercial quantum dots (Qdots) 565 under...
