In vitro interaction of potential antiviral TMPRSS2 inhibitors with human serum albumin and cytochrome P 450 isoenzymes. Biomed Pharmacother 2022; 146:112513. [PMID: 34915414 PMCID: PMC8668183 DOI: 10.1016/j.biopha.2021.112513] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2021] [Revised: 11/24/2021] [Accepted: 12/06/2021] [Indexed: 01/25/2023] Open
Abstract
The interactions of four sulfonylated Phe(3-Am)-derived inhibitors (MI-432, MI-463, MI-482 and MI-1900) of type II transmembrane serine proteases (TTSP) such as transmembrane protease serine 2 (TMPRSS2) were examined with serum albumin and cytochrome P450 (CYP) isoenzymes. Complex formation with albumin was investigated using fluorescence spectroscopy. Furthermore, microsomal hepatic CYP1A2, 2C9, 2C19 and 3A4 activities in presence of these inhibitors were determined using fluorometric assays. The inhibitory effects of these compounds on human recombinant CYP3A4 enzyme were also examined. In addition, microsomal stability assays (60-min long) were performed using an UPLC-MS/MS method to determine depletion percentage values of each compound. The inhibitors showed no or only weak interactions with albumin, and did not inhibit CYP1A2, 2C9 and 2C19. However, the compounds tested proved to be potent inhibitors of CYP3A4 in both assays performed. Within one hour, 20%, 12%, 14% and 25% of inhibitors MI-432, MI-463, MI-482 and MI-1900, respectively, were degraded. As essential host cell factor for the replication of the pandemic SARS-CoV-2, the TTSP TMPRSS2 emerged as an important target in drug design. Our study provides further preclinical data on the characterization of this type of inhibitors for numerous trypsin-like serine proteases.

Abstract
The transmembrane serine protease, TMPRSS2 is an important target in the treatment of seasonal influenza infections and contributes to prostate carcinogenesis and metastasis. In this study, the effect of the synthetic TMPRSS2 inhibitor I-432 on jejunal IPEC-J2 cell monolayers cultured on membrane inserts was characterized. Using a fluorogenic substrate, it was found that the apical addition of I-432 could suppress trypsin-like activity in the supernatants of IPEC-J2 cells. The inhibition of TMPRSS2 did not affect physiologically produced hydrogen peroxide levels in the apical and in basolateral compartments. Loss of expression of the TMPRSS2 serine protease domain (28 kDa) was also observed when cells were pre-exposed to I-432. Partial decrease in immunofluorescent signal intensities derived from the altered distribution pattern of TMPRSS2 was detected after a 48 h long incubation of IPEC-J2 cells with the inhibitor indicating the efficacy of TMPRSS2 inhibition via I-432 administration in vitro.
