The hypothesis that cytoplasmic proteases play a functional role in programmed cell death was tested by examining the effect of protease inhibitors on the T cell receptor-mediated death of the 2B4 murine T cell hybridoma and activated T cells. The cysteine protease inhibitors trans-epoxysuccininyl-L-leucylamido-(4-guanidino) butane (E-64) and leupeptin, the calpain selective inhibitor acetyl-le...
Recently a new virus strain designated as SARS coronavirus result in fatal pandemic known COVID-19. Bioinformatics and drug screening are directed for the assessment of potential inhibitors before their clinical implementation treatment this pneumonia. One expected natural potent is Portulaca oleracea which has been assigned an effective to different human ailments throughout whole world. P. wi...
The Bowman-Birk protease inhibitors from soybeans and chick peas suppress in vitro malignant transformation. This fluorescent microscopy study is designed to visualize the cellular site of action of these protease inhibitors. Binding and internalization of active protease inhibitors occur over a time course of 2 h. The rate and character of fluorescent micro graphs obtained are compared to insu...
The vast majority of protein protease inhibitors bind their targets in a substrate-like manner. This is a robust and efficient mechanism of inhibition but, due to the highly conserved architecture of protease active sites, these inhibitors often exhibit promiscuity. Inhibitors that show strict specificity for one protease usually achieve this selectivity by combining substrate-like binding in t...
Protease inhibitors play a role in regulating proteases during cellular development and in plant defense. We cloned and sequenced cDNA encoding six protease inhibitors expressed in soybean roots infected with soybean cyst nematode (SCN) and determined their expression patterns. Four of these protease inhibitors are novel and have not been reported previously. Using RT-PCR, we measured the relat...
Increased susceptibility to the protease inhibitors saquinavir and amprenavir has been observed in human immunodeficiency virus type 1 (HIV-1) with specific mutations in protease (V82T and N88S). Increased susceptibility to ritonavir has also been described in some viruses from antiretroviral agent-naive patients with primary HIV-1 infection in association with combinations of amino acid change...
Specific inhibitors of hepatitis C virus (HCV) replication that target the NS3/4A protease (e.g., VX-950) or the NS5B polymerase (e.g., R1479/R1626, PSI-6130/R7128, NM107/NM283, and HCV-796) have advanced into clinical development. Treatment of patients with VX-950 or HCV-796 rapidly selected for drug-resistant variants after a 14-day monotherapy treatment period. However, no viral resistance w...
Human immunodeficiency virus type 1 (HIV-1) protease inhibitors comprise an important class of drugs used in HIV treatments. However, mutations of protease genes accelerated by low fidelity of reverse transcriptase yield drug resistant mutants of reduced affinities for the inhibitors. This problem is considered to be a serious barrier against HIV treatment for the foreseeable future. In this st...
Background: The novel coronavirus SARS-CoV-2 has severely affected the health and economy of several countries. Multiple studies are in progress to design therapeutics against potential target proteins SARS-CoV-2, including 3CL protease, an essential protein for virus replication. Materials & methods: In this study we employed deep neural network-based generative predictive models de novo s...
We previously showed that HIV-1 protease inhibitors slowed the proliferation of human myeloid leukemia cells and enhanced their differentiation in the presence of all-trans retinoic acid (ATRA). In this study, we found that protease inhibitors, including ritonavir, saquinavir, and nelfinavir, but not indinavir, induced growth arrest and apoptosis of U266, RPMI8226, and ARH77 human multiple myel...
