  [d4U]-butyne-[HI-236] as a non-cleavable, bifunctional NRTI/NNRTI HIV-1 reverse-transcriptase inhibitor

  摘要：

  The synthesis of bifunctional compound 10 consisting of d4U joined at C-5 to a butynyl spacer attached to HI-236 is reported using a Sonogashira coupling as a key step. As a non-cleavable bifunctional HIV inhibitor incorporating an NRTI with an NNRTI, 10 shows good inhibitory activity (EC50 = 250 nM) against HIV (IIIB) replication in NIT-2 cell culture, which is eight times greater than that of d4T and between those of the two component drugs.

  propargyl-4-PEG (15d) have been synthesized and biologically evaluated as RT inhibitors against HIV-1. The key step in their synthesis involved a Sonogashira coupling of 5-iodo d4U’s benzoate with an alkynylated tethered HI-236 precursor followed by introduction of the HI-236 thiourea functionality. Biological evaluation in both cell-culture (MT-2 cells) as well as using an in vitro RT assay revealed 15a–c to

  Several novel thiourea derivatives of the NNRTI HI-236 substituted at the C-2 oxygen of the phenyl ring have been synthesized and evaluated for their inhibitory activity against HIV-1 ( IIIB) replication in MT-2 cell cultures. The compounds were synthesized in order to fine-tune the activity of HI-236 as well as to gain insight into spatial characteristics in the pocket pertaining to the positional choice of tether in the design of [NRTI]-tether-[HI-236] bifunctional inhibitors. Two of the thiourea derivatives bearing a butynyl (6c) or hydroxyethyl tether (6n) were endowed with improved anti-HIV activity compared to HI-236. NNRTI activity was confirmed by a cell-free RT assay on six of the derivatives in which 6c returned an IC50 of 3.8 nM compared to 28 nM for HI-236, establishing it as an improved lead for HI-236. The structure-activity pro. le is discussed in terms of potential interactions in the NNRTI pocket as suggested by a docking model using AutoDock, which have a bearing on the bifunctional drug design.
