ABSTRACT
|
|
|
| |
|
The potent new antiviral inhibitor TMC-114 (UIC-94017) of HIV-1 protease (PR)
has been studied with three PR variants containing single mutations D30N, I50V,
and L90M, which provide resistance to the major clinical inhibitors. The
inhibition constants (K(i)) of TMC-114 for mutants PR(D30N), PR(I50V), and
PR(L90M) were 30-, 9-, and 0.14-fold, respectively, relative to wild-type PR.
The molecular basis for the inhibition was analyzed using high-resolution
(1.22-1.45 A) crystal structures of PR mutant complexes with TMC-114. In
PR(D30N), the inhibitor has a water-mediated interaction with the side chain of
Asn30 rather than the direct interaction observed in PR, which is consistent
with the relative inhibition. Similarly, in PR(I50V) the inhibitor loses
favorable hydrophobic interactions with the side chain of Val50. TMC-114 has
additional van der Waals contacts in PR(L90M) structure compared to the PR
structure, leading to a tighter binding of the inhibitor. The observed changes
in PR structure and activity are discussed in relation to the potential for
development of resistant mutants on exposure to TMC-114.

Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
