Enantioselective organocatalytic fluorination-induced Wagner-Meerwein rearrangement.
Despite the fact that only 21 fluorinated molecules are known to be biosynthesized, it is notable that about 20–25% of all modern pharmaceuticals and agrochemicals incorporate at least one fluorine atom. Nevertheless, the practice of introducing fluorine atoms into bioactive compounds is rather recent, as the first synthetic fluorinated drug, namely 5-fluorouracil, was synthesized as late as in...
متن کاملNew Antithrombotic Aryl-sulfonylthiosemicarbazide Derivatives Synthesized from Natural Safrole
No âmbito de uma linha de pesquisas que trata da síntese e avaliação farmacológica de novos candidatos a protótipos de agentes antitrombóticos, explorando a hibridação molecular como estratégia de planejamento estrutural, descrevemos neste trabalho a síntese e avaliação farmacológica de novas sulfonilsemicarbazidas (10a-d), planejadas por analogia estrutural a antagonistas de receptores de TXA2...
متن کاملdetermination of olanzapine and thiourea using electrodes modified by dna and film of copper-cobalt hexacyanoferrate & investigation of electro-oxidation of some catechol derivatives in the presence of 4-phenylsemicarbazid
چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...
15 صفحه اولDesign, synthesis, and SAR study of isopropoxy allylbenzene derivatives as 15-lipoxygenase inhibitors
Objective(s): Allylbenzenes have been recently developed as inhibitors of lipoxygenases. They decrease peroxidation activity via mimicking 1,4-unsaturated bonds of fatty acids by their allyl portion. We designed and synthesized new derivatives of allyl benzenes (6a-f) with isopropoxy and amide substituents at ortho and meta positions towards allyl group, respectively. ...
متن کاملNew catechol derivatives of safrole and their antiproliferative activity towards breast cancer cells.
Catechols were synthesized from safrole. Nine derivatives were prepared and assessed for antiproliferative effects using different human cell lines. The in vitro growth inhibition assay was based on the sulphorhodamine dye to quantify cell viability. The derivatives 4-allylbenzene-1,2-diol (3), 4 4-[3-(acetyloxy)propyl]-1,2-phenylene diacetate (6) and 4-[3-(acetyloxy)propyl]-5-nitro-1,2-phenyle...
