CBR-2092 is a DNA-directed RNA polymerase and DNA topoisomerase inhibitor. CBR-2092 exhibited rifampin-like potency as an inhibitor of RNA polymerase, was an equipotent (balanced) inhibitor of DNA gyrase and DNA topoisomerase IV, and retained activity against a prevalent quinolone-resistant variant. Studies of mutant strains that exhibited reduced susceptibility to CBR-2092 further substantiated RNA polymerase as the primary cellular target of CBR-2092, with DNA gyrase and DNA topoisomerase IV being secondary and tertiary targets, respectively, in strains exhibiting preexisting rifampin resistance.
CBR-470-2, a glycine-substituted analog, exhibits the capacity to activate NRF2 signaling, making it a valuable compound for investigating glycolysis modulation in scientific research [1].
CBR-6672, a type II NADH dehydrogenase inhibitor, demonstrates potent antimycobacterial activity against mycobacterium tuberculosis (Mtb) with a minimum inhibitory concentration (MIC) of 0.14 μM [1].
PROTAC BRD2/BRD4 degrader-1 (compound 15) serves as a potent, selective degrader of BET proteins BRD4 and BRD2, achieving rapid, reversible, and unexpectedly selective elimination of BRD4 and BRD2 compared to BRD3. Its efficacy in suppressing solid tumors manifest with minimal cytotoxic effects. This compound comprises a BET inhibitor, a connecting linker, and thalidomide as the ligand for cereblon (CRBN)/cullin 4A[1].
PROTAC BRD4-binding moiety 1 is a BRD4 ligand that binds to the cereblon ligand through a linker, enabling the formation of a PROTAC complex. This complex efficiently degrades BRD4[1].
Desmethyl-QCA276, the QCA276-based moiety, binds to cereblon ligand via a linker to form PROTAC to degrade BET. QCA276 is a BET inhibitor with an IC50 of 10 nM, and with a Ki of 2.3 nM[1].
