Calpains are cytosolic, Ca(2+)-activated, neutral cysteine proteases. Rabbit renal proximal tubule (RPT) cells express both mu- and m-calpain. Although multiple calpain inhibitors protect against RPT cell death, most calpain inhibitors lack specificity, membrane permeability, and/or potency. A group of novel catalytic site-directed calpain inhibitors, including chloroacetic acid N'-[6,7-dichlor...
The reaction of 3-cyclohexyl-2-(cyclohexylimino)-6-(4-ethoxyphenyl)-5-(4-methyl-3-oxo-3,4-dihydroquinoxalin-2-yl)-2,3-dihydro-4H-1,3-oxazin-4-one with ammonium acetate afforded 3-(1-cyclohexyl-2-(cyclohexylamino)-4-(4-ethoxyphenyl)-6-oxo-1,6-dihydropyrimidin-5-yl)-1-methylquinoxalin-2(1H)-one in a good yield. compound was fully characterized.
Reaction of Cd(OAc)2·2H2O and selenourea in primary-amine/secondary-amine cosolvent mixtures affords crystalline CdSe quantum platelets at room temperature. Their crystallinity is established by X-ray diffraction analysis (XRD), high-resolution transmission electron microscopy (TEM), and their sharp extinction and photoluminescence spectra. Reaction monitoring establishes the magic-size nanoclu...
در این بررسی دو سری کمپلکس از کبالت (iii) به فرمول های کلی (co(do)(doh)pn)(amine)cl][pf6:(amine=imazl,analin) , [co(salpn)(amine)2]x:(amine=pprdn, prldn,mrplin,imdzl),(x=bph4 , clo4) سنتز و با استفاده از آنالیز عنصری و روشهای طیف سنجی h-nmr , ir , uv-vis شناسایی گردیده است. به علت حساسیت ترکیبات با لیگاندهای چهار دندانه ای به آب برای سنتز آنها تمهیدات خاصی به کار برده شده است. تا بتوا...
It is reported that two derivatives of (Z)-3-(quinolin-2-ylmethylene)-3,4-dihydroquinoxalin-2-(1H)-one (1) with a tetraphenylethene (TPE) group introduced at amide N atom of the dihydroquinoxalinone moiety (2) or at phenyl ring of the quinoline fragment (3) are synthesized, and the derivatives exhibit a remarkably enhanced aggregation-induced emission (AIE) activity than the parent. Although bo...
