  The Synthesis and Thymidylate Synthase Inhibitory Activity of L-.gamma.-L-Linked Dipeptide and L-.gamma.-Amide Analogs of 2-Desamino-2-methyl-N10-propargyl-5,8-dideazafolic acid (ICI 198583)

  摘要：

  Sixteen gamma-linked dipeptide and four L-Glu-gamma-amide analogues of 2-desamino-2-methyl-N-10-propargyl-5,8-dideazafolic acid (ICI 198583) have been synthesized and evaluated as inhibitors of thymidylate synthase (TS). Z-blocked L-Glu-gamma-L-linked dipeptides and L-Glu-gamma-amides were prepared by condensing alpha-tert-butyl-N-(benzyloxycarbonyl)-L-glutamic acid with the appropriate tert-butyl-protected L-amino acid or amine. The Z group was removed by catalytic hydrogenolysis, and the resulting dipeptides or L-Glu-gamma-amides were condensed with the appropriate pteroic acid analogue trifluoroacetate salt using diethyl cyanophosphoridate as coupling reagent. Deprotection with trifluoroacetic acid in the final step gave the desired quinazoline gamma-linked dipeptides and L-Glu-gamma-amides as their trifluoroacetate salts. Nearly all the dipeptide analogues were potent inhibitors of TS, the best being ICI 198583-gamma-L-2-aminoadipate (IC50 = 2 nM). Several of these dipeptides were found to be susceptible to enzymatic hydrolysis in mice. The quinazoline monocarboxylate L-Glu-gamma-amides, lacking an alpha'-carboxyl group, are less active against TS and L1210 cell growth but are also not susceptible to enzymatic hydrolysis in mice.

  Highly enantioselective monoalkylation of p-chlorobenzaldehyde imine of glycine tert-butyl ester under mild phase-transfer conditions

  摘要：

  The selective monoalkylation of glycine tert-butyl ester aldimine Schiff base 3 has been realized in high chemical yield with excellent enantioselectivity under mild liquid-liquid phase-transfer conditions by the use of binaphthyl-derived chiral quaternary ammonium bromides 7 and 8 as catalysts. This achievement demonstrates that 3 can be used as a cost-effective substrate for the preparation of optically active alpha-alkyl-alpha-amino, acid derivatives by chiral phase-transfer catalysis.

  Modelling studies suggest that the core α-amino hydroxamic acid residues appear to influence the relative potencies via specific inhibitor-peptidase interactions, including short fluorine–hydrogen contacts, within the enzyme’s pockets. The binding of the essential hydroxamate group to the zinc ion is rather unaffected by the rest of the molecule. In contrast, the corresponding α-aminocarboxylic acid derivatives

  基质金属蛋白酶（MMPs）参与许多生理和病理过程，例如动脉粥样硬化和肿瘤发生，其中MMPs的上调是主要的。合成了基于异羟肟酸酯的非肽型广谱MMP抑制剂（MMPI）CGS 27023A的氟化类似物，并使用荧光体外测定法测量了纳摩尔范围内MMP-2和MMP-9的抑制能力。本文报道的氟化MMPI的抑制能力在某些情况下与它们的非氟化类似物相当或什至更好。与铅结构相反，氟化MMP的两种对映异构体几乎同样有效。建模研究表明，核心的α-氨基异羟肟酸残基似乎通过特定的抑制剂-肽酶相互作用影响相对效能，在酶的口袋内包括短的氢氟接触。必需异羟肟酸酯基团与锌离子的结合几乎不受分子其余部分的影响。相反，相应的α-氨基羧酸衍生物为10效力降低3倍，甚至失效。
