CR 39, a plastic, can be used as a charged particle detector for superimposed autoradiography tissue images.

CR4056 (6-(1H-imidazol-1-yl)-2-phenylquinazoline) is a selective inhibitor of MAO-A with IC50 of 202.7 nM and a ligand of I2-imidazoline receptor with IC50 of 596 nM.

2,3,5,6-Tetramethoxyaporphine, a benzyl isoquinoline alkaloid with antitussive properties, can be extracted from Glaucium flavum Cr. (Family Papaveraceae) [1] [2].

AP 811 acetate is a selective antagonist of the atrial natriuretic peptide clearance receptor (ANP-CR, NPR3), demonstrating high affinity with a K_i value of 0.48 nM and exhibiting over 20,000-fold selectivity for NPR3 compared to NPR1. It effectively inhibits ANP-induced pump stimulation [1] [2].

(R)-CR8 ((R)-Isomer) is a potent and selective CDK inhibitor.

Anti-SARS-CoV-2 Spike mAb (CR3022) is a human monoclonal IgG1 antibody derived from CHO cells. It specifically targets the S1 domain of the Spike protein in both SARS-CoV and SARS-CoV-2.

Itriglumide (CR-2945) is a cholecystokinin (CCK)-2 receptor antagonist with antisecretory and antiulcerogenic properties.

(S)-CR8 is an effective second-generation cyclin-dependent kinase inhibitor.

(R)-CR8 trihydrochloride (CR8, (R)-Isomer trihydrochloride) is a CDK1/2/5/7/9 inhibitor that acts as a molecular glue degrader with neuroprotective activity and induces apoptosis.
