  CCK-B agonist or antagonist activities of structurally hindered and peptidase-resistant Boc-CCK4 derivatives

  摘要：

  Replacement of Met31 by (N-Me)Nle in CCK8 or CCK4 has been shown to improve the affinity and selectivity for CCK-B receptors. In order to obtain molecules with enhanced bioavailability, two novel series of protected tetrapeptides of the general formula Boc-Trp30-X-Asp-Y33 have been developed. Introduction of (N-Me)Nle and the bulky, aromatic naphthylalaninamide (Nal-NH2) in positions X and Y, respectively, does not greatly modify the affinity for guinea pig brain CCK-B receptors. In contrast, incorporation of hindering N-methyl amino acids such as (N-Me)Phe, (N-Me)Phg, or (N-Me)Chg, but not their non-methylated counterparts, in position X induced a large decrease in affinity for the CCK-B binding sites. Among the various peptides synthesized, Boc-[(N-Me)Nle31,1Nal-NH233]CCK4 (2) (K(I) = 2.8 nM), Boc-[Phg31,1Nal-NH233]CCK4 (15) (K(I) = 14 nM), and Boc-[Phg31,1Nal-N(CH3)233]CCK4 (17) (K(I) = 39 nM) displayed good affinities for brain CCK-B receptors and had good selectivity ratios. These pseudopeptides, in which the presence of unnatural and hydrophobic residues is expected to improve their penetration of the central nervous system, were shown to be very resistant to brain peptidases. Interestingly, whereas compounds 2 and 15 proved to be full agonists for rat hippocampal CCK-B receptors when measured in an electrophysiological assay, compound 17 behaved as a potent antagonist in the same test and displayed a good affinity in rat brain K(I)(CCK-B) = 51 nM as compared to the Merck antagonist L365,260, K(I)(CCK-B) = 12 nM. This illustrates a simple means to obtain CCK-B antagonists and suggests that the free, CONH2 group plays a critical role in the recognition of the agonist date of brain CCK-B receptors.

  A series of compounds based on the carboxyl-terminal CAAL sequence of PGGTase-I substrates was designed and synthesized. Using piperazin-2-one as a semi-rigid scaffold, we have introduced critical pharmacophores in a well-defined arrangement to mimic the CAAL sequence. High potency and exceptional selectivity were obtained for inhibition of PGGTase-I with structures such as 45 and 70. Potency of this series of GGTIs was dependent on the presence of an L-leucine residue with a free carboxyl terminus, as well as an S configuration of the 3-aryl group. The selectivity was significantly enhanced by 5-methyl substitution on the imidazole ring and fluorine substitution on the 3-aryl group. Modification of the 6-position of the piperazinone scaffold was found to be unfavorable. Compounds 44 and 69, the corresponding methyl esters of 45 and 70, were found to selectively block processing of Rap1A by PGGTase-I in whole cells with IC50 values of 0.4 µM and 0.7 µM respectively.

  基于PGGTase-I底物的羧端CAAL序列，设计并合成了一系列化合物。我们利用哌嗪-2-酮作为半刚性骨架，在明确有序的排列中引入了关键的药效团，以模拟CAAL序列。对于抑制PGGTase-I，如45和70结构所展现，其活性高且选择性极佳。这一系列GGTIs的活性依赖于具有自由羧端的L-亮氨酸残基以及3-芳基的S构型。通过咪唑环上的5-甲基取代和3-芳基上的氟取代，其选择性显著提升。发现对哌嗪酮骨架的6位进行修饰是不利的。化合物44和69，即45和70的相应甲酯，分别以0.4 µM和0.7 µM的IC50值选择性地阻断PGGTase-I对Rap1A的细胞内加工。
