    The NS3 protease of hepatitis C virus (HCV) has emerged as one of the best characterized targets for next-generation HCV therapy. The tetrapeptide 1 and pentapeptide 2 are alpha-ketoamide-type HCV serine protease inhibitors with modest potency. We envisioned that the 1,2,3,4-tetrahydroisoquinoline-3-carboxylamide (Tic) moiety could be cyclized to the P3 capping group. The resulting macrocycle could
    丙型肝炎病毒(HCV)的NS3蛋白酶已成为下一代HCV治疗的最有特色的靶标之一。四肽1和五肽2是具有中等效力的α-酮酰胺型HCV丝氨酸蛋白酶抑制剂。我们设想了1,2,3,4-四氢异喹啉-3-羧酰胺(Tic)部分可以被环化为P3封端基团。所得的大环化合物可通过其与Ala156甲基的额外接触来增强结合。大环化还可以提供肽含量较低的HCV抑制剂。从二肽5开始合成,其是通过两个氨基酸生物的偶联而获得的。将N-末端封端为庚-6-烯酰胺,得到6。双键的氢化得到醇7,大环8的前体。在Mitsunobu条件下实现了大环化(PPh(3),ADDP)。然后,将大环酸9与适当的右侧片段12、14或16结合,该片段由共同的中间体11制备。最后,α-羟酰胺的氧化提供了目标分子α-酮酰胺17、18和21。然后将末端酯加工成羧酸19和20,以及酰胺20和23。在HCV 蛋白酶连续测定中测试了抑制剂17-23。

We have designed, preorganized, and depeptidized macrocyclic inhibitors from P(4) to P(2)' and optimized binding to 0.1 microM. The structure of an inhibitor bound to the enzyme was also solved.

The macrocyclic alpha-ketoamides were active inhibitors of the HCV NS3 protease, with the C-terminal acids and amides being more potent than tert-butyl esters.

  • Novel Potent Hepatitis C Virus NS3 Serine Protease Inhibitors Derived from Proline-Based Macrocycles

    The hepatitis C virus (HCV) NS3 protease is essential for viral replication. It has been a target of choice for intensive drug discovery research. On the basis of an active pentapeptide inhibitor, 1, we envisioned that macrocyclization from the P2 proline to P3 capping could enhance binding to the backbone Ala156 residue and the S4 pocket. Thus, a number of P2 proline-based macrocyclic alpha-ketoamide inhibitors were prepared and investigated in an HCV NS3 serine protease continuous assay (K-i*). The biological activity varied substantially depending on factors such as the ring size, number of amino acid residues, number of methyl substituents, type of heteroatom in the linker, P3 residue, and configuration at the proline C-4 center. The pentapeptide inhibitors were very potent, with the C-terminal acids and amides being the most active ones (24, K-i* = 8 nM). The tetrapeptides and tripeptides were less potent. Sixteen- and seventeen-membered macrocyclic compounds were equally potent, while fifteen-membered analogues were slightly less active. gem-Dimethyl substituents at the linker improved the potency of all inhibitors (the best compound was 45, Ki* = 6 nM). The combination of tert-leucine at P3 and dimethyl substituents at the linker in compound 47 realized a selectivity of 307 against human neutrophil elastase. Compound 45 had an IC50 of 130 nM in a cellular replicon assay, while IC50 for 24 was 400 nM. Several compounds had excellent subcutaneous AUC and bioavailability in rats. Although tripeptide compound 40 was 97% orally bioavailable, larger pentapeptides generally had low oral bioavailability. The X-ray crystal structure of compounds 24 and 45 bound to the protease demonstrated the close interaction of the macrocycle with the Ala156 methyl group and S4 pocket. The strategy of macrocyclization has been proved to be successful in improving potency (> 20-fold greater than that of 1) and in structural depeptization.
