  胆囊收缩素的C端五肽类似物中的二羰基和相关部分取代甘氨酸：CCK（2）激动剂显示一种新型的结合模式。

  摘要：

  胆囊收缩素领域的最新进展表明可能发生CCK（2）受体的多个亲和状态。此外，进行“体外”和“体内”的许多药理实验支持与CCK（2）配体相关的不同药理学谱的可能。确实，一些激动剂本质上是焦虑症，并且在记忆力测试中无效，而另一些激动剂不是焦虑症，并且看起来能够增强记忆力。后一种情况的参考化合物是CCK-8类似物BC 264（Boc-Tyr（SO（3）H）-gNle-mGly-Trp-（NMe）Nle-Asp-Phe-NH（2））。但是，尽管已知基于CCK-4（Trp-Met-Asp-Phe-NH（2））的四肽配体具有足够的结构特征以识别CCK（2），但没有一个具有BC 264的特性。因此，我们开发了含有BC 264 C端四肽的新型短肽或伪肽衍生物。我们的结果表明，某些化合物的特征是在N端存在两个羰基，如2b（HO（2） C-CH（2）-CONH-Trp-（NMe）Nle-Asp-Phe-NH（2））可能显示BC

  The rates and pathways of decarboxylation of acetic acid derivatives, RCO2H, and their Na+ salts, RCO2Na, which possess electron-withdrawing groups (R = CCl3-, CF3-, HOC(O)CH2-, NH2C(O)CH2-, CF3CH2-, NCCH2-, CH3C(O)-) were determined in H2O at 100-260 degrees C and a pressure of 275 bar. Simple conversion to RH + CO2 occurs in most cases, except that H2O appears to be a required reactant for the anions. Real-time FTIR spectroscopy was used to determine the rate of formation of CO2 in flow reactors constructed of 316 stainless steel (SS) and of titanium. With a few exceptions, the rate of decarboxylation is similar within the 95% confidence interval in 316 SS and Ti and the difference is smaller than that caused by R. Therefore, while wall effects/catalysis may exist in some cases, it plays a lesser role in the relative rates than the substituent R. The acid form of the keto derivatives decarboxylates more rapidly than the anionic form, whereas the reverse is true for the nonketo derivatives. In keeping with the greater role of H2O as a reactant, the entropy of activation for the anions is smaller or more negative than for the acids. A Taft plot of the decarboxylation rates suggests that the mechanistic details can be interpreted in terms of the various roles of R. Where R = HOC(O)CH2- and NH2C(O)CH2-, decarboxylation occurs faster than expected, probably because a cyclic transition state can exist. The rate is slower than expected for R = CF3-, perhaps because of stabilization of the acid by hyperconjugation. The mechanism of decarboxylation of acids of the remaining R groups is similar and the steric effect of R is somewhat more influential than its electron withdrawing power.

  known to possess sufficient structural features for CCK(2) recognition, none shares the properties of BC 264. Hence we have developed new short peptidic or pseudo-peptidic derivatives containing the C-terminal tetrapeptide of BC 264. Our results indicate that some compounds characterized by the presence of two carbonyl groups at the N-terminus, as in 2b (HO(2)C-CH(2)-CONH-Trp-(NMe)Nle-Asp-Phe-NH(2)), are
