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.

(-)-Syringaresinol
0 Images(-)-Syringaresinol is an orally active isomer of syringaresinol (HY-N8307) found in Annona Montana. (-)-Syringaresinol exhibits antioxidant, anti-inflammatory, and anticancer activities. (-)-Syringaresinol can alleviate ulcerative colitis via the PI3K-Akt/MAPK/Wnt signaling pathway. (-)-Syringaresinol inhibits HL-60 cell proliferation by arresting the G1 phase and inducing apoptosis. (-)-Syringaresinol inhibits LPS (HY-D1056)-induced microglial activation by downregulating the NF-κB p65 signaling pathway and its interaction with ERβ, exerting anti-neuroinflammatory effects.

(1R,3R)-RSL3
0 Images(1R,3R)-RSL3 is an isomer of RSL3 (HY-100218A). RSL3 ((1S,3R)-RSL3) is an inhibitor of glutathione peroxidase 4 (GPX4) (ferroptosis activator), reduces the expression of GPX4 protein, and induces ferroptotic death of head and neck cancer cell. RSL3 increases the expression of p62 and Nrf2 and inactivates Keap1 in HN3-rslR cells.

Emtricitabine triphosphate tetrasodium salt
0 ImagesSynonyms: (-)-Emtricitabine triphosphate tetrasodium saltEmtricitabine triphosphate tetrasodium salt ((-)-Emtricitabine triphosphate tetrasodium salt) is the phosphorylated active metabolite of Emtricitabine (HY-17427). Emtricitabine triphosphate inhibits HIV-1 reverse transcriptase and incorporates into the nascent viral DNA chain, causing chain termination. Emtricitabine triphosphate tetrasodium salt can serve as a biomarker for assessing adherence to antiretroviral therapy. Emtricitabine triphosphate (tetrasodium salt) can be used in research related to HIV infection.

SHP2-D26 isomer-1
0 ImagesSHP2-D26 isomer-1 (Compound 26) is an isomer of SHP2-D26 (HY-145162). SHP2-D26 is the first highly potent SHP2 PROTAC degrader. The induction of SHP2 degradation by SHP2-D26 requires binding to VHL-1 and SHP2 proteins, and is dependent on ubiquitin-like modification and the proteasome. SHP2-D26 can be used in the research of esophageal cancer and acute myeloid leukemia.
