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.

Oxiran-2-ylmethanol
0 ImagesOxiran-2-ylmethanol (Glycidol) is an ester product. Oxiran-2-ylmethanol induces base pair point mutations in bacterial strains and structural chromosome aberrations in cultured cells. Oxiran-2-ylmethanol forms N-(2,3-dihydroxypropyl)valine hemoglobin adducts. Oxiran-2-ylmethanol acts as an animal carcinogen but does not significantly induce micronucleated immature erythrocytes in animal bone marrow. Oxiran-2-ylmethanol enables anionic polymerization to produce linear poly(glycidol). Oxiran-2-ylmethanol can be used for cancer-related research.

L-Ribose
0 ImagesL-Ribose is the enantiomer of D-ribose (HY-113375). L-Ribose replaces D-ribose to synthesize L-ribonucleic acid in cells, leading to erroneous gene transcription. L-Ribose serves as a starting material for L-nucleoside analogs, glycoconjugates and oligonucleotides. L-Ribose can be used in research related to hepatitis B virus infection, hepatitis C virus infection, hepatitis D virus infection, Epstein-Barr virus infection and cytomegalovirus infection.

(-)-Enitociclib
0 ImagesSynonyms: (R)-Enitociclib; (-)-BAY-1251152; (-)-VIP152(-)-Enitociclib ((R)-Enitociclib) is an enantiomer of Enitociclib (HY-103019E) with an optical rotation of (-). Enitociclib is a selective CDK9 inhibitor and apoptosis inducer. Enitociclib inhibits CDK9 activity and reduces the phosphorylation of Ser2 in the carboxyl-terminal domain (CTD) of RNA polymerase Pol II, thereby downregulating the transcription of key oncogenes such as MYC and MCL1. Enitociclib has anti-proliferative activity targeting MYC+ lymphoma and multiple myeloma (MM) cells, and has synergistic effects with Bortezomib (HY-10227) and Lenalidomide (HY-A0003), and can be used in the research of hematological malignancies.

(±)-Dihydroactinidiolide
0 Images(±)-Dihydroactinidiolide is the dextrorotatory form of Dihydroactinidiolide (HY-107805). (±)-Dihydroactinidiolide has a strong, pleasant musky, tea-like and tobacco-like aroma and is mainly found in black tea, tobacco and fruits. (±)-Dihydroactinidiolide has antioxidant activity and can be derived from β-carotene.or light adaptation in Arabidopsis.

(-)-Gallocatechin
0 Images(-)-Gallocatechin, an epimer of (-)-Epigallocatechin (EGC) (HY-N0225), is contained in various tea products. (-)-Gallocatechin demonstrates antioxidant activity in vitro, including inhibition of LDL oxidation and DPPH radical scavenging.
-
D-Lysine
0 ImagesD-Lysine is the D-enantiomer of L-Lysine (HY-N0469). D-Lysine is metabolically inert and not utilized for protein synthesis by mammalian ribosomes. D-Lysine 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 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 can be used in research related to cancer and diabetes.

KI696 isomer
0 ImagesKI696 isomer is an isomer of KI696 (HY-101140). KI696 is a selective KEAP1/NRF2 protein-protein interaction inhibitor with a human Kd value of 1.3 nM. KI696 acts by competitively occupying the NRF2-binding pocket of the KEAP1 Kelch domain. KI696 blocks KEAP1-mediated ubiquitination and degradation of NRF2, promotes the translocation of NRF2 to the nucleus, activates the expression of downstream antioxidant genes, increases intracellular glutathione levels, and alleviates oxidative stress-induced cell damage and inflammatory cell infiltration in the lungs. KI696 reduces ozone-induced pulmonary oxidative damage and inflammatory cell accumulation in rats, and upregulates pulmonary antioxidant genes. KI696 can be used in research related to chronic obstructive pulmonary disease, oxidative stress and inflammation.
