GSK4112 (SR6452) is a Rev-erbα agonist with EC50 of 0.4 μM, also is a small molecule chemical probe for the cell biology of the nuclear heme receptor Rev-erbα.

CLK8 is a selective CLOCK inhibitor that binds to and interferes with CLOCK activity, disrupts the interaction between CLOCK and BMAL1, and modulates circadian rhythm amplitude.CLK8 can be used to study circadian rhythm-related disorders.

STL1267, a potent REV-ERB agonist capable of crossing the blood-brain barrier, exhibits a K i value of 0.16 µM for REV-ERBα without demonstrating cytotoxicity. It effectively inhibits the gene expression of BMAL1.

KS15 is a chemical compound that acts as an inhibitor on the interactions between cryptochromes, specifically CRY1 and CRY2, and the CLOCK: BMAL1 heterodimer. This compound, with an EC50 value of 4.9 μM, hinders the feedback actions of CRYs on E-box-dependent transcription. The CLOCK: BMAL1 heterodimer is a vital transcriptional regulator for the mammalian circadian clock. In addition, KS15 exhibits significant anti-proliferative activity.
