  New bidentates as full inhibitors of enkephalin-degrading enzymes: synthesis and analgesic properties

  摘要：

  New compounds were designed to fully inhibit the in vitro metabolism of enkephalins, ensured by three different metallopeptidases. For this purpose, bidentate ligands as hydroxamate and N-hydroxy-N-formylamino groups were selected as highly potent metal coordinating agents and introduced on Phe-Gly and Phe-Ala related structures. Compounds corresponding to the general formula HC(O)N(OH)CH2CH(CH2Ph)CONHCH2COOH (compound 7) and HN(OH)C(O)CH2CH(CH2Ph)CONHCH(R)COOH (compound 11, R = H; compound 13, R = CH3) behave as full inhibitors of the three enzymes, with IC50's in the nanomolar range for enkephalinase, from 0.3 microM to 1 nM for dipeptidylaminopeptidase, and in the micromolar range for a biologically relevant aminopeptidase. Two diastereoisomers of the most active inhibitor 13 were separated by HPLC and their stereochemistry was assigned by 1H NMR spectroscopy. Both isomers were efficient as enkephalinase blockers, but only the RS isomer, designated kelatorphan, was able to strongly inhibit aminopeptidase and dipeptidylaminopeptidase. Intracerebroventricular injection in mice of these mixed inhibitors, especially kelatorphan, led to naloxone reversible analgesic responses (hot-plate test) that were slightly better than those produced by a mixture of thiorphan and bestatin, two potent inhibitors of enkephalinase and aminopeptidase, respectively. Kelatorphan was also more efficient in potentiating the analgesia induced by a subanalgesic dose of Met-enkephalin. All these results support a physiological role in pain transmission for enkephalinase and a probably synaptic aminopeptidase M.

  环状RGD肽类似物可作为抗血小板抗血栓药。

  摘要：

  血小板的刺激激活异源二聚体整联蛋白受体GPIIbIIIa结合纤维蛋白原（Fg），从而导致血小板聚集。GPIIbIIIa / Fg结合抑制剂潜在地适合于在溶栓治疗期间和之后作为抗血栓形成剂的急性使用。将三肽序列Arg-Gly-Asp（RGD）（许多整联蛋白配体的常见结构元件）掺入环状肽中，可制得一系列具有一般结构的BrAc-（AA1）-RGD-Cys-OH肽。通过固相肽合成。通过在高稀释度下在pH为8的条件下使N末端溴乙酰基与半胱氨酸巯基反应来完成环化反应，生成硫醚桥连的环肽[cyclo-S-Ac-（AA1）-RGD-Cys-OH]。使用α-取代的溴乙酰基产生了一系列类似的乙酰基取代的硫醚桥连环肽。硫醚的氧化产生可分离的非对映异构亚砜桥接的环肽。在GPIIbIIIa ELISA分析和血小板凝集分析中进行全面评估后，选择G-4120（70A； AA1 = D-Tyr；亚砜桥）作为抗血栓形成剂进

  The bromodomain and extra-terminal proteins (BET) have emerged as promising therapeutic targets for the treatment of castration-resistant prostate cancer (CRPC). We report the design, synthesis and evaluation of a new series of benzoxazinone-containing 3,5-dimethylisoxazole derivatives as selective BET inhibitors. One of the new compounds, (R)-12 (Y02234), binds to BRD4(1) with a Kd value of 110 nM
