Pellitorine kills Aedes aegypti mosquito larvae by inhibiting* V-type H⁺-ATPase and aquaporin 4 (AaAQP4). Pellitorine exhibits anti-cancer activity (e.g., leukemia and breast cancer) and has inhibitory effects on certain bacteria.

HY-B0083S1

Leflunomide-13C6
Leflunomide- ¹³C₆ (HWA486- ¹³C₆) is ¹³C labeled Leflunomide. Leflunomide is a pyrimidine synthesis inhibitor, inhibiting dihydroorotate dehydrogenase (DHODH), and acts as a disease-modifying antirheumatic agent.

HY-15510S

Tenovin-6-d6
Tenovin-6-d₆ is the deuterium labeled Tenovin-6 (HY-15510). Tenovin-6, an analog of Tenovin-1 (HY-13423), is an activator of p53 transcriptional activity. Tenovin-6 inhibits the protein deacetylase activities of purified human SIRT1, SIRT2, and SIRT3 with IC₅₀s of 21 μM, 10 μM, and 67 μM, respectively. Tenovin-6 also inhibits dihydroorotate dehydrogenase (DHODH).
