Puzerinostat
Based on 1 Customer Validation
Puzerinostat (Purinostat) is a highly selective class I/IIb histone deacetylase (HDAC) inhibitor, with IC50 values of 0.81 nM, 1.4 nM, 1.7 nM, 3.8 nM, 11.5 nM, and 1.1 nM against HDAC1, HDAC2, HDAC3, HDAC8, HDAC6, and HDAC10, respectively. Puzerinostat enhances glutamine metabolism by upregulating GLS1. Puzerinostat induces cell Apoptosis and downregulates the expression of BCR-ABL and c-MYC. Puzerinostat delays the progression of Ph+ B-cell acute lymphoblastic leukemia and prolongs the survival of relevant mouse models. Puzerinostat regulates the immune microenvironment. Puzerinostat can be used in research related to chronic myeloid leukemia, Philadelphia chromosome-positive B-cell acute lymphoblastic leukemia, relapsed/refractory multiple myeloma, relapsed/refractory lymphoma, diffuse large B-cell lymphoma, and double-expression lymphoma.

Puzerinostat (20 nM; 0-48 h) induces time-dependent hyperacetylation of α-tubulin and histone H3 in LAMA84 Ph+ chronic myeloid leukemia cells[1].
Puzerinostat is a highly selective class I/IIb HDAC inhibitor with favorable cardiac safety profiles due to its weak inhibitory effect on hERG channels[3].
Puzerinostat (10-200 nM; 24-72 h) potently reduces the viability of LAMA84 and K562 Ph+ chronic myeloid leukemia cells, with an IC50 of less than 10 nM, and its effect is dose- and time-dependent[1].
Puzerinostat (72 h) potently inhibits the proliferation of multiple myeloma (MM) and lymphoma cell lines, with all IC50 values below 5 nM[3].
Treatment with Puzerinostat (5-150 nM; 24 h) induces dose-dependent G0/G1 cell cycle arrest in LAMA84 and K562 Ph+ chronic myeloid leukemia cells[1].
Puzerinostat (0.25-0.5 nM; 24 h) upregulates the expression of MHC-I and MHC-II on MM1S cells in a concentration-dependent manner[3].

Puzerinostat (5-10 mg/kg; i.p., i.v.; three times per week; for 5 consecutive weeks) significantly prolongs survival and eliminates leukemia cells in BL-2 secondary transplanted Ph+ B-ALL mouse models, with 60% of mice surviving up to day 100 at the dose of 10 mg/kg[2].
Puzerinostat (2.5-10 mg/kg) significantly prolongs survival and reduces tumor burden in PDX models of Ph+ B-ALL relapsed after tyrosine kinase inhibitor treatment, with a median overall survival (OS) of 73 days in the 10 mg/kg dose group[2].
Puzerinostat (10 mg/kg) significantly extends the median survival to 86 days, reduces serum calcium levels, ameliorates osteolytic lesions, and enhances innate and adaptive anti-tumor immune responses in the 5TMM mouse model[3].
