Production of Protease Inhibitor With Penicillium sp. — Optimization of the Medium for Growth in Pellet Form and Cytotoxicity Testing [PDF]

Engineering in Life Sciences
Penicillium sp. (IBWF 040‐09) produces a protease inhibitor that can potentially be used against the main protease of human African trypanosomiasis. Since the target substance is formed intracellularly (under nutrient limitation), the fungal pellet is ...

A TIL-Type Serine Protease Inhibitor Involved in Humoral Immune Response of Asian Corn Borer Ostrinia furnaculis

Frontiers in Immunology, 2022
To elucidate the application value of insect endogenous protease and its inhibitor genes in pest control, we analyzed in detail the transcriptome sequence of the Asian corn borer, Ostrinia furnacalis.

Oxidative profile and protease regulator potential to predict sperm functionality in donkey (Equus asinus)

Scientific Reports, 2021
Seminal plasma (SP) of donkey stallions was evaluated using various oxidative stress parameters as well as protease and protease inhibitor activities. SP was obtained by nine donkey stallions.

HIV-1 Gag Non-Cleavage Site PI Resistance Mutations Stabilize Protease/Gag Substrate Complexes In Silico via a Substrate-Clamp

BioChem, 2021
HIV-1 protease active site inhibitors are a key part of antiretroviral therapy, though resistance can evolve rendering therapy ineffective. Protease inhibitor resistance typically starts with primary mutations around the active site, which reduces ...

SjAPI, the first functionally characterized Ascaris-type protease inhibitor from animal venoms. [PDF]

PLoS ONE, 2013
Serine protease inhibitors act as modulators of serine proteases, playing important roles in protecting animal toxin peptides from degradation. However, all known serine protease inhibitors discovered thus far from animal venom belong to the Kunitz-type ...

Time to treatment disruption in children with HIV-1 randomized to initial antiretroviral therapy with protease inhibitors versus non-nucleoside reverse transcriptase inhibitors.

PLoS ONE, 2020
BackgroundChoice of initial antiretroviral therapy regimen may help children with HIV maintain optimal, continuous therapy. We assessed treatment-naïve children for differences in time to treatment disruption across randomly-assigned protease inhibitor ...

Mastering the canonical loop of serine protease inhibitors: enhancing potency by optimising the internal hydrogen bond network. [PDF]

PLoS ONE, 2011
BACKGROUND: Canonical serine protease inhibitors commonly bind to their targets through a rigid loop stabilised by an internal hydrogen bond network and disulfide bond(s).

Hepatitis C virus drugs that inhibit SARS-CoV-2 papain-like protease synergize with remdesivir to suppress viral replication in cell culture

Cell Reports, 2021
Summary: Effective control of COVID-19 requires antivirals directed against SARS-CoV-2. We assessed 10 hepatitis C virus (HCV) protease-inhibitor drugs as potential SARS-CoV-2 antivirals. There is a striking structural similarity of the substrate binding

HIV-1 protease inhibitor mutations affect the development of HIV-1 resistance to the maturation inhibitor bevirimat

Retrovirology, 2011
Background Maturation inhibitors are an experimental class of antiretrovirals that inhibit Human Immunodeficiency Virus (HIV) particle maturation, the structural rearrangement required to form infectious virus particles.

Structural determinants for subnanomolar inhibition of the secreted aspartic protease Sapp1p from Candida parapsilosis

Journal of Enzyme Inhibition and Medicinal Chemistry, 2021
Pathogenic Candida albicans yeasts frequently cause infections in hospitals. Antifungal drugs lose effectiveness due to other Candida species and resistance. New medications are thus required. Secreted aspartic protease of C.
