Drug Isomer
Drug Isomer
Drug isomers are compounds with the same molecular formula but different atomic arrangements or spatial configurations. They are divided into structural isomers and stereoisomers, and have different biological activities, safety and metabolic characteristics. Drug isomers can be used as drug improvement groups or drug efficacy control groups. For example, Carvedilol has higher bioavailability and better safety than (R)-Carvedilol.

D-Lysine monohydrochloride
0 ImagesD-Lysine monohydrochloride is the D-enantiomer of L-Lysine (HY-N0469). D-Lysine monohydrochloride is metabolically inert and not utilized for protein synthesis by mammalian ribosomes. D-Lysine monohydrochloride blocks renal uptake of 111In/90Y-Octreotide (HY-P0036)-based probes without inhibiting uptake by tumor/receptor tissues, and thus acts as a renoprotective agent in diagnostic imaging and peptide receptor radionuclide therapy (PRRT). D-Lysine monohydrochloride specifically inhibits the early steps of non-enzymatic glycation by competing with glucose via its free amino group, theoretically, it can serve as a glycation competitor that "does not interfere with protein synthesis" under chronic hyperglycemia in diabetes. D-Lysine monohydrochloride can be used in research related to cancer and diabetes.

(R)-Zelebrudomide
0 ImagesSynonyms: (R)-NX-2127(R)-Zelebrudomide ((R)-NX-2127) is an isomer of Zelebrudomide (HY-153220). Zelebrudomide is an orally active BTK-targeting PROTAC degrader, with DC50 values of 4.5 nM and 31 nM against wild-type BTK and BTKC481S mutant, respectively. Zelebrudomide recruits the cereblon E3 ubiquitin ligase complex to mediate the degradation of BTK. Zelebrudomide also acts as a molecular glue to bind the cereblon E3 ubiquitin ligase complex, mediating the degradation of IKZF1 and IKZF3. Zelebrudomide can be used in the research of B-cell malignancies.
