Abstract
Structural analysis of modern pharmaceutical practices allows for the identification of two rapidly growing trends: the introduction of tailor-made amino acids and the exploitation of fluorinated motifs. Curiously, the former represents one of the most ubiquitous classes of naturally occurring compounds, whereas the latter is the most xenobiotic and comprised virtually entirely of man-made derivatives. Herein, 39 selected compounds, featuring both of these traits in the same molecule, are profiled. The total synthesis, source of the corresponding amino acids and fluorinated residues, and medicinal chemistry aspects and biological properties of the molecules are discussed.

Abstract
HCV NS3/4A serine protease inhibitors are the first class of direct acting antivirals (DAA) introduced in clinical practice. The first generation agents, selective against HCV genotype 1, are used in association with pegylated interferons and ribavirin allowing increased cure rates at the price of increased toxicity, significant drug interactions and high risk of selecting mutants conferring cross-resistance to the entire class. A large number of second-wave HCV protease inhibitors are currently in clinical development. Advancements include higher potency, activity against a wider number of genotypes, improved tolerability, easier dosing schedules, although their genetic barrier to resistance remains low, especially for subtype 1a, except for the most recent grazoprevir and ACH-2684. The most relevant progress regards the combination with other classes of DAA allowing construction of interferon-free regimens of short duration, good tolerability with exceptionally high cure rates.

All-oral therapy with nucleotide inhibitors sofosbuvir and GS-0938 for 14 days in treatment-naive genotype 1 hepatitis C (nuclear). J Viral Hepat 2013; 20:699-707. [PMID: 24010644 DOI: 10.1111/jvh.12091] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2013] [Accepted: 02/01/2013] [Indexed: 12/12/2022]
Abstract
Sofosbuvir and GS-0938 are distinct nucleotide analogues with activity against hepatitis C virus (HCV) in vitro. We evaluated the antiviral activity and safety of sofosbuvir and GS-0938 alone and in combination in HCV genotype 1 patients. In this double-blind study, 40 treatment-naïve patients were randomly assigned to 4 treatment cohorts: (i) GS-0938 for 14 days, (ii) GS-0938 for 7 days followed by GS-0938 plus sofosbuvir for 7 days, (iii) sofosbuvir for 7 days followed by GS-0938 plus sofosbuvir for 7 days and (iv) GS-0938 plus sofosbuvir for 14 days. In each arm, 8 patients received active drug and 2 placebo. After 7 days of dosing, patients in all 4 dose groups experienced substantial reductions in HCV RNA, with median declines (Q1, Q3) of -4.50 (-4.66, -4.24) in Cohort 1, -4.55 (-4.97, -4.13) in Cohort 2, -4.65 (-4.78, -4.17) in Cohort 3 and -4.43 (-4.81, -4.13) in Cohort 4; patients receiving placebo had essentially no change in HCV RNA (+0.07 log(10) IU/mL). Seven days after the end of treatment, the proportions of patients with HCV RNA <15 IU/mL were 4 (50%), 8 (100%), 7 (88%) and 5 (63%) for Cohorts 1-4, respectively, vs 0 for placebo. No viral breakthrough or resistance mutations were observed. No serious adverse events or Grade 3 or 4 adverse events were reported. Sofosbuvir and GS-0938-alone and in combination--were well tolerated and led to substantial reductions in viral load. Sofosbuvir is undergoing further investigation as a possible backbone of an all-oral regimen for chronic HCV.

Abstract
Hepatitis C virus (HCV) infection continues to represent a major health issue, with estimates of 130–170 million people infected worldwide. Recent developments in the HCV NS3/4a protease inhibitor area have significantly improved treatment options for patients. However, a more dramatic paradigm shift in the treatment of HCV infection appears all but certain in coming years, with a move to all oral combination therapy with direct‐acting antivirals (DAAs). HCV protease inhibitors have the potential to play a significant role in these DAA combination therapies. This chapter discusses in detail the design and discovery of three HCV NS3/4a protease inhibitors in clinical development: simeprevir (TMC‐435350), vaniprevir (MK‐7009) and MK‐5172.
