人类T细胞嗜淋巴/白血病病毒1型(HTLV-I)可引起成人T细胞淋巴瘤/白血病。该病毒还导致慢性进行性脊髓病和几种炎症性疾病。为了停止生产新的病毒成分,在我们之前的报告中,我们获得了在P3残基上具有重要的酰胺封端部分的四肽HTLV-I蛋白酶抑制剂。在本研究中,我们去除了P3-帽部分,并费了很大的劲才优化了P3残基对HTLV-I蛋白酶的抑制效力。我们发现了一个非常有效和小的四肽HTLV-I酶抑制剂(KNI-10774a,IC50=13 nm)。
The human T cell lymphotropic/leukemia virus type 1 (HTLV-I) causes adult T cell lymphoma/leukemia. The virus is also responsible for chronic progressive myelopathy and several inflammatory diseases. To stop the manufacturing of new viral components, in our previous reports, we derived small tetrapeptidic HTLV-I protease inhibitors with an important amide-capping moiety at the P3residue. In the current study, we removed the P3-cap moiety and, with great difficulty, optimized the P3residue for HTLV-I protease inhibition potency. We discovered a very potent and small tetrapeptidic HTLV-I protease inhibitor (KNI-10774a, IC50=13nM).
