aprotic diazotization of anthranilic acid with isoamylnitrite or amylnitrite gave benzenediazonium-2- carboxylate. subsequent thermal decomposition of this diazonium salt (in situ) in 1,2-dichloroethane as a solvent at 85oc and in the presence of 2,5-diethyl-3,4-diphenylcyclopentadienonaes a trapping agent gave 1,4-diethyl-2, 3-diphenylnaphthalene in high yield, after loss of carbon monoxide. a...

There is considerable interest in exploiting metallosupramolecular cages as drug delivery vectors. Recently, we developed a [Pd2L4](4+) cage capable of binding two molecules of cisplatin. Unfortunately, this first generation cage was rapidly decomposed by common biologically relevant nucleophiles. In an effort to improve the kinetic stability of these cage architectures here we report the synth...

Various derivatives of adenosine were prepared by acylation of adenosine (6-amino-9-(bD-ribofuranosyl)purine (1) with different molar equivalents of acetic anhydride and/or pivaloyl chloride in pyridine. Compounds 6-acetylamino-9-[(2,3,5-tri-O-acetyl)-b-Dribofuranosyl]purine (3), 6-amino-9-[(2,3,5-tri-O-acetyl)-b-D-ribofuranosyl]purine (4), and 6-pivaloylamino-9-[(2,3,5-tri-O-pivaloyl)-b-D-ribo...

BACKGROUND The nicotine metabolite ratio (NMR or 3-hydroxycotinine/cotinine) has been used to phenotype CYP2A6-mediated nicotine metabolism. Our objectives were to analyze (i) the stability of NMR in plasma, saliva, and blood in various storage conditions, (ii) the relationship between NMRs derived from blood, plasma, saliva, and urine, and (iii) the reproducibility of plasma NMR in ad libitum ...

آموزش دانشگاهی نوعی از آموزش است که در دورۀ جدید به حوزۀ معماری وارد شده است، این نوع آموزش فرض ها و مقتضیات خود را به طور ضمنی بر معماری حمل می کند. یکی از فرض های اساسی آموزش دانشگاهی معماری فهم «معماری به منزلۀ یک رشته یا دیسیپلین دانشگاهی» است. ساخت گشایی از این فرض اساسی برای فهم موقعیت امروزین معماری بسیار مهم است. مطالعۀ تاریخی مفهوم دیسیپلین نشان می دهد که این مفهوم، ضمن حمل معنای انضبا...
