cryptochrome

KL 001 is a Cryptochrome protein (CRY) stabilizer. KL001 prevented ubiquitin-dependent degradation of CRY, resulting in lengthening of the circadian period. KL001-mediated CRY stabilization inhibited glucagon-induced gluconeogenesis in primary hepatocytes. KL001 thus provides a tool to study the regulation of CRY-dependent physiology and aid development of clock-based therapeutics of diabetes.

KL201, a circadian clock modulator, is an isoform-selective cryptochrome 1 (CRY1) stabilizer that lengthens the period of circadian rhythms in cells and tissues [1].

SHP1705 is a potent and selective Cryptochrome 2 (CRY2) activator with circadian rhythm-modulating activity. It inhibits BMAL1-CLOCK transcriptional activity and prolongs survival in glioblastoma (GBM) mice established from glioblastoma stem cells (GSCs).

KL044 is a cryptochrome 1 (CRY1) activator that prolongs circadian rhythms and inhibits PER2 activity. KL044 inhibits melanogenesis by inhibiting the cAMP/PKA/CREB pathway.

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.

4-Hydroxychalcone (P-Cinnamoylphenol) attenuates hyperaldosteronism, inflammation, and renal injury in cryptochrome-null mice.

ISOTHIAZOLINE 1,1-DIOXIDE (isothiazolidine 1,1-dioxide) is a reactant used in the synthesis of orally bioavailable hebatits B caspid inhibitors, and in the preparation of cryptochrome imhibitors as antidiabetic agents.

TH301 acts as a stabilizer for cryptochrome circadian regulator 2 (CRY2). It demonstrates selectivity by stabilizing CRY2 over CRY1 in a degradation assay conducted with HEK293 cells expressing CRY reporters at concentrations ranging from 0.1 to 10 µM. In wild-type mouse fibroblasts, TH301 extends the circadian period, but this effect is absent in Cry2-/- fibroblasts. Additionally, it boosts rosiglitazone-dependent induction of brown adipose tissue-specific genes such as Ucp1, Cidea, and Kcnk3 in primary mouse stromal vascular fractions.

KS15 is a cryptochrome (CRY) inhibitor that promotes G1 cell cycle arrest, enhances drug sensitivity in MCF-7 cells, and exhibits antitumour activity against human breast cancer cells.

M47 is a selective CRY1 (Cryptochrome 1) degradator that enhances nuclear degradation of CRY1 and disrupts its stability, thereby extending the lifespan of p53 knockout mice. It facilitates research into various cancers involving p53 mutations.
