In silico study on identification of novel MALT1 allosteric inhibitors.

ABSTRACT: Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1), which plays a crucial role in the nuclear factor-kappa B (NF-κB) activation signaling pathway as a paracaspase, is a new target for immunomodulatory and antitumor drugs. Here, novel inhibitors that target MALT1 allosteric sites were identified by virtual screening FDA-approved drug databases. Paliperidone, a compound that binds to the allosteric site of MALT1, is investigated. An in vitro study found that the proteolytic activity of MALT1 substrate cleavage was blocked by paliperidone. Meanwhile, the MALT1 proteolytic activity was reversible, as demonstrated by the partial recovery of the MALT1 substrate cleavage following compound wash out. The docking analysis of the interaction of MALT1 and paliperidone s
