Caspase-1 and -3 Inhibiting Drimane Sesquiterpenoids from the Extremophilic Fungus Penicillium solitum
摘要:
Two new drimane sesquiterpene lactones and one new tricarboxylic acid derivative were isolated from the Berkeley Pit extremophilic fungus Penicillium solitum. The structures of these compounds were deduced by spectroscopic analysis. Berkedrimanes A and B inhibited the signal transduction enzymes caspase-1 and caspase-3 and mitigated the production of interleukin 1-beta in the induced THP-1 (pro-monocytic leukemia cell line) assay.
Provided herein are compositions and methods for the treatment of a patient having an HIV-1 infection and/or AIDS. More specifically this invention provides treatment of an HIV-1 infection and/or AIDS using small molecule compounds, such as inhibitors for the activation and/or activity of caspase-1. Inhibitors for the activation and/or activity of caspase-1 also prevent the cell death of CD4 T-cells in a population of CD4 T-cells comprising HIV-1 infected CD4 T-cells and uninfected CD4 T-cells. In addition, caspase-1 inhibitors inhibit inflammation, and pyroptosis.
