The design, synthesis and activity of non-ATP competitive inhibitors of pp60c-src tyrosine kinase.Part 1: Hydroxynaphthalene derivatives
摘要:
A series of hydroxynaphthalene pp60(c-src) non-peptide inhibitors was designed, using the crystal structure of the insulin receptor tyrosine kinase as a qualitative model, to target the peptide substrate binding site. Representative inhibitors were shown to bind non-competitively with respect to ATP. (C) 2000 Elsevier Science Ltd. All rights reserved.

halide catalyst differentiates between the in-situ-generated P-species in the A-T process, mainly involving phosphorylchloride and phosphoric anhydride, thus leading to highly enantiodivergent O-phosphorylation reactions. Furthermore hydrogen bonding interactions between the catalysts and phosphorus molecules were crucial in asymmetric induction.
公开了一种高度对映发散的有机催化方法,通过受二肽-鏻盐催化的 Atherton-Todd (AT) 反应启发的动力学拆分合成阻转异构联芳基化合物。这种灵活的方法通过微调具有优异选择性因子的双功能鏻,产生R - 和S - 对映异构体(s) 分别高达 1057 和 525。轴向手性有机磷化合物的合成说明了新合成的 O-磷酸化联芳二醇的潜力。机理研究表明,双功能卤化鏻催化剂区分了 AT 过程中原位生成的 P 物种,主要涉及磷酰氯和磷酸酐,从而导致高度对映发散的 O-磷酸化反应。此外,催化剂和磷分子之间的氢键相互作用在不对称诱导中至关重要。

The present invention provides a method for identifying inhibitors of protein kinases. Methods are also provided for inhibiting protein kinase activity. Specific non-peptide protein tyrosine kinase inhibitors are provided. The protein kinases produced using the method of the present invention may be used to treat a number of conditions in patients, including cancer, psoriasis, atherosclerosis, or immune system activity.
An efficient enantioselectiveoxidativecoupling of 2-naphtholderivatives based on a concept of dual activation catalysis is realized. A chiral dinuclear vanadium(IV) complex (Ra,S,S)-1e possessing (S)-tert-leucine moieties at the 3,3′-positions of the (R)-binaphthyl skeleton was developed, which was found to promote the oxidativecoupling of 2-naphthol to afford (S)-BINOL with 91% ee.

A group of new 4-[2-(7-heterocyclemethoxynaftalen-2-ylmethoxy)ethyl]benzoic acids have been synthesized and pharmacologically evaluated as LTD(4)-antagonists. Thiazole derivatives, especially 4-[2-[7-(4-cyclobutylthiazole-2-ylmethoxyl)naphthalen- 2-ylmetho-xy]et hyl]benzoic acid, present considerable activity and improved pharmacokinetic profiles in comparison with our quinoline containing lead molecule

A series of carba- or oxa[5]-, [6]-, [7]-, and -[19]helicene (di)thiols was prepared. The Miyazaki-Newman-Kwart rearrangement of (dimethylcarbamothioyl)oxy (oxa)helicenes in a flow reactor or nucleophilic substitution of dichloro (oxa)helicenes with alkanethiolates were used in the sulfanylation step. Despite the high temperatures employed in this key step, no conformational scrambling was observed
