Discovery and structural diversity of the hepatitis C virus NS3/4A serine protease inhibitor series leading to clinical candidate IDX320.
Parsy CC, Alexandre FR, Bidau V, Bonnaterre F, Brandt G, Caillet C, Cappelle S, Chaves D, Convard T, Derock M, Gloux D, Griffon Y, Lallos LB, Leroy F, Liuzzi M, Loi AG, Moulat L, Chiara M, Rahali H, Roques V, Rosinovsky E, Savin S, Seifer M, Standring D, Surleraux D

Exploration of the P2 region by mimicking the proline motif found in BILN2061 resulted in the discovery of two series of potent HCV NS3/4A protease inhibitors. X-ray crystal structure of the ligand in contact with the NS3/4A protein and modulation of the quinoline heterocyclic region by structure based design and modeling allowed for the optimization of enzyme potency and cellular activity. This research led to the selection of clinical candidate IDX320 having good genotype coverage and pharmacokinetic properties in various species.

Immunoglobulin G (IgG) and IgA, but also nonantibody factors, account for in vitro neutralization of human immunodeficiency virus (HIV) type 1 primary isolates by serum and plasma of HIV-infected patients.

The factors present in serum and plasma samples of human immunodeficiency virus (HIV)-infected patients that are responsible for the neutralization of four HIV type 1 (HIV-1) primary isolates in vitro have been analyzed. Purification of immunoglobulins (Ig) by affinity chromatography showed that the activities were mostly attributable to IgG and less frequently to IgA. For two samples, we have shown that the high-level and broad-spectrum inhibitory activity was essentially caused by non-Ig factors interfering with the measurement of antibody-specific neutralizing activity.
