Synthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines
A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...

A new 2-[(4-substituted-phenyl-3-chloroazetidin-2-one)-5-(2'-methylamino 4-phenyl-1', 3'-thiazolyl-]-1, 3, 4-thiadiazoles, 5(a-n) were synthesized from 2-substituted-benzylideneamino-5-[2'-methylamino-4'-phenyl-1',3'-thiazolyl]-1,3, 4-thiadiazole, 4(a-n) using 2-amino-4phenyl-1, 3-thiazole as a starting material. The synthesised compounds have been screened in vitro for their antimicrobial acti...
متن کاملSynthesis and Characterization of Soluble Polyimides Derived from 2,2*-Bis(3,4-dicarboxyphenoxy)-9,9*- spirobifluorene Dianhydride
The synthesis of aromatic poly(ether imide)s containing spirobifluorene units in the polymer backbone is described. 2,29-Bis(3,4-dicarboxyphenoxy)-9,99-spirobifluorene dianhydride, which was used as a new monomer, was synthesized with 2,29-dihydroxy-9,99-spirobifluorene as the starting material. In the spiro-segment, the rings of the connected bifluorene were orthogonally arranged. This bis(eth...
متن کاملSTUDIES ON HYDRALAZINES - PART-1x1 PREPARATION AND ANTIMICROBIAL ACTIVITY OF 1 - (PHTHALAZIN- 1 '-YLAMINO)- 3-CHLORO-4-ARYL- 4H-(OR 4-METHYL)-2-AZETIDINONE
1- (Phthalazin-l'-yl-amino)-3-chloro-4-aryl-4H-(4o-rm ethyl)-2-azetidinones (3) were prepared by cycloaddition of-methyl substituted benzal hydrazinophthalazine (2) with chloro acetylchloride. The hydrazone (2) was synthesised by the condensation of 1- hydrazinophthalazine (1) with substituted aromatic aldehydes, ketones 7 acetophenones. 1- Hydrazinophthalazine was prepared from the phthal...
