(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.

SHP2-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.

(Rac)-Hydnocarpin is a flavonoid isolated from Hydnocarpus anthelminthica, and exhibits moderate cytotoxic on cancer cells.

(R,S,R)-ML334 is the isomer of ML334 (HY-110258), and can be used as an experimental control. ML334 is a potent, cell permeable activator of NRF2 by inhibition of Keap1-NRF2 protein-protein interaction. ML334 binds to Keap1 Kelch domain with a K_d of 1 μM. ML334 stimulates NRF2 expression and nuclear translocation and induces antioxidant response elements (ARE) activity.

(Z)-JIB-04 (NSC693627) is the Z isomer of JIB-04 that has two forms, E (HY-13953) and Z isomers. (Z)-JIB-04 is inactive in epigenetic analysis.

AU-16235 is an inactive epimer of AU-15330. AU-16235 has no effect on cancer cell survival and growth

R-(–)-Flecainide is an orally active antiarrhythmic agent, which inhibits ventricular ectopic activity.

(S)-ARI-1 is an S-enantiomer of ARI-1. ARI-1 is a ROR1 inhibitor and apoptosis inducer, used in NSCLC research.

Golgicide A-1 (GCA-1) is a less active cis-diastereomer of Golgicide A (GCA). Golgicide A-1 weakly inhibits mosquito reproduction.

(R)-Vitamin D2 is the isomer of Vitamin D2 (HY-76542), and can be used as an experimental control. Vitamin D2 (Ergocalciferol), drived from plant sources or dietary supplements, could be used as supplement of Vitamin D.

(1R,3R)-RSL3 (Standard) is the analytical standard of (1R,3R)-RSL3 (HY-100218C). This product is intended for research and analytical applications. (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.

(S)-Imlunestrant ((S)-LY-3484356) tosylate is an (S)-enantiomer of Imlunestrant (HY-145572). (S)-Imlunestrant tosylate can be used in research of cancer.

15(R)-Iloprost is the unnatural or inverted C-15 epimer of lloprost (HY-A0096).

(22R)-Budesonide-d₈ ((22R)-BUD-d₈) is the deuterium labeled (22R)-Budesonide. (22R)-Budesonide ((22R)-BUD) is the (22R)-enantiomer of Budesonide (HY-13580). (22R)-Budesonide is a non-halogenated glucocorticoid with high local anti-inflammatory activity.

Desmethylmirtazapine (Standard) is the analytical standard of Desmethylmirtazapine. This product is intended for research and analytical applications. Desmethylmirtazapine is an active metabolite of Mirtazapine that has antidepressant effects.

7β-O-Methylmorroniside (7R-O-methylmorroniside) is a R-isomer of 7-O-Methyl morroniside.

NVP-CGM097 (stereoisomer) is a stereoisomer of NVP-CGM097, with no special bioactivity. NVP-CGM097 is a potent and selective MDM2 inhibitor.

(S,S)-Ketone monoester is a (S,S)-enantiomer of Ketone monoester (HY-15344). Ketone monoester elevates the AcAc and acetone levels, thereby produces sustained ketosis and significantly delays central nervous system oxygen toxicity (CNS-OT) seizures.

11β-Prostaglandin F1β (11β-PGF1β) is a stereoisomer of PGF1α with inverted C-9 and C-11 hydroxyl groups.
