Tirabrutinib is a Selective BTK Inhibitor

The BTK kinases comprise 5 structural domains, including pleckstrin homology, TEC homology, Src homology, Src homology, and kinase domains. The activation of BTK kinase depends on recruitment to the plasma membrane via the pleckstrin homology domain. In humans, BTK mutations result in arrested B-cell development. Besides, it leads to...

Repotrectinib is a potent ROS1 and TRK Inhibitor

Repotrectinib is a potent ROS1 (IC50=0.07 nM) and TRK (IC50=0.83/0.05/0.1 nM for TRKA/B/C) inhibitor. The IC50 values are 0.83/0.05/0.1 nM for TRKA/B/C, respectively. Repotrectinib potently inhibits WT ALK (IC50=1.01 nM). Repotrectinib inhibits mutant ALKs. It inhibits ALK G1202R with an IC50 of 1.26 nM. Besides, it inhibits ALK L1196M with an IC50 of 1.08 nM)....

Apitolisib is an Orally Active Class I PI3K and mTORC1/2 Inhibitor

Activation of the pathway occurs following activating point mutations or amplification of the PIK3CA gene encoding the p110a PI3K isoform. Oncogenes such as PI3K, AKT, epidermal growth factor receptor (EGFR), and human epithelial growth factor receptor 2 (HER2) stimulate proliferation, growth, and survival by activating mTOR kinase. The mTOR...

PR-104A is a Hypoxia-Selective DNA Cross-Linking Agent and Cytotoxin

PR-104, like TH-302, is a prodrug of nitrogen mustard that has shown some degree of efficacy in adult patients with relapsed/refractory acute myeloid leukemia (AML). PR-104A (SN 27858) is the alcohol metabolite of phosphate prodrug PR-104. PR-104A is a hypoxia-selective DNA cross-linking agent/DNA-damaging agent and cytotoxin. Therefore, this compound...

Iberdomide (CC-220) is an Orally Active Cereblon (CRBN) E3 Ligase Modulator (CELMoD)

Cereblon (CRBN) is a key protein in autosomal recessive nonsyndromic mental retardation. Specifically, it plays an intermediary role in helping immunomodulatory drugs play their immunomodulatory and tumor-killing roles. Besides, CRBN is highly conserved from plants to mammals, and mRNA expression in humans, rats, and mice is common. CRBN interacts...
