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 ...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...

امروزه تنوع محصولات پلیمری سنتزی بسیار بالا می باشد اما پیشرفت های اخیر به جای استفاده از طراحی پرهزینه جهت تولید یک ماده جدید، روند اصلاح مواد را در بر گرفته است. روش پلیمری شدن رادیکال آزاد کنترل شده/ زنده امکان سنتز و تولید دامنه ی وسیعی از محصولات پلیمری و مواد جدید را با ساختارهای از پیش تعیین شده در شرایط فرآیندی آسان تر نسبت به روش پلیمری شدن یونی فراهم می کند. فرایند انتقال به زنجیر افز...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
this study describes the organic synthesis of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxy benzofuran-6-ol (spbf) as an example of a benzofuran derivative used as a new series of amyloid imaging agents. these benzofuran derivatives may be useful amyloid imaging agents for detecting b-amyloid plagues in the brain of alzheimer’s disease. the precursor is 1-[6-hydroxy-4-methoxybenzofuran-5-yl]-p...
