  Phenol-derived CVFM analog inhibitors of Ras Farnesyltransferase possessing cellular in vitro activity 1

  摘要：

  A study was performed on structure-activity relationships of a series of phenol-derived, CVFM analogs, inhibitors of Pas Farnesyltransferase (FTase). The effect of various substituents on the phenol ring was examined, while the VFM moiety of the potent inhibitor CVFM was kept constant. The FTase inhibitory activity, reported as IC50 in table I, was influenced by both the chemical properties and the relative position of the substituents on the phenolic ring. The most active compounds in this series contained a chloro or bromine substituent on the phenolic ring. Subsequently we have tested the effects of these FTase inhibitors on the anchorage-dependent growth of two rat epithelial cell lines, FRTL-5 and the same line v-Ha-ras transformed, While most of the compounds were inactive, two showed a growth inhibitory effect: compound 4 was active against normal as well against transformed cells while derivative 13 was active only against transformed cells.

  Stereoisomers and analogues of amastatin, [(2S, 3R)-3-amino-2-hydroxy-5-methylhexanoyl]-L-Val-L-Val-L-Asp, were synthesized and their inhibitory activities towards aminopeptidase A (AP-A) and other arylamidases tested. Among the four stereoisomers of a new amino acid residue in amastatin, the 2S stereoisomers exhibited strong activity. In a series of compounds in which the C-terminal amino acid of amastatin was substituted by other amino acids, the one containing Asp or Glu showed the strongest activity towards AP-A. In a series of compounds in which the second or third residue from the amino terminal of amastatin was substituted by other amino acids, the one containing hydrophobic amino acids showed strong activity. In the study of the relationship of the length of the peptide chain and inhibitory activity, the activity towards AP-A was seen to increase until the length of the peptide reached that of a tetrapeptide.

  阿马司他（(2S,3R)-3-氨基-2-羟基-5-甲基己酰基-L-缬氨酰-L-缬氨酰-L-天冬氨酸）的立体异构体和类似物被合成，并测试了它们对氨基肽酶A（AP-A）和其他芳基酰胺酶的抑制活性。在阿马司他中一个新的氨基酸残基的四种立体异构体中，2S立体异构体表现出强烈的活性。在一系列将阿马司他C端氨基酸替换为其他氨基酸的化合物中，含有Asp或Glu的化合物对AP-A显示出最强的活性。在一系列将阿马司他从氨基端开始的第二个或第三个残基替换为其他氨基酸的化合物中，含有疏水氨基酸的化合物表现出强烈的活性。在研究肽链长度与抑制活性关系的研究中，随着肽链长度达到四肽水平，对AP-A的活性逐渐增加。

  Peptide-based compounds including heteroatom-containing, three-membered rings efficiently and selectively inhibit specific activities of N-terminal nucleophile (Ntn) hydrolases associated with the proteasome. The peptide-based compounds include an epoxide or aziridine, and functionalization at the N-terminus. Among other therapeutic utilities, the peptide-based compounds are expected to display anti-inflammatory properties and inhibition of cell proliferation. Oral administration of these peptide-based proteasome inhibitors is possible due to their bioavailability profiles

  An efficient and concise strategy for the synthesis of cyclic dipeptides via Pd-catalyzed site-selective δ-C(sp2)–H amination/fluorination and N-to-C cyclization is disclosed. The backbone amides within the dipeptides serves as endogenous directing groups, while the desired products were switched by the C-terminal ester group. This chemistry presents a novel and robust alternative to construct cyclodipeptide

  We report the design, synthesis, and biological evaluation of imidazopyridine-based peptidomimetics based on the substrate consensus sequence of Akt, an AGC family serine/threonine kinase hyperactivated in over 50% of human tumors. Our ligand-based approach led to the identification of novel substrate mimetic inhibitors of Akt1 featuring an unnatural extended dipeptide surrogate. Compound 11 inhibits Akt isoforms in the sub-micromolar range and exhibits improved proteolytic stability relative to a parent pentapeptide.
