Endoxifen Z-isomer(Cat No.:I000461)is an active metabolite of tamoxifen, a selective estrogen receptor modulator (SERM) used in the treatment of estrogen receptor-positive (ER+) breast cancer. The Z-isomer form is particularly potent, directly binding to estrogen receptors and inhibiting estrogen-driven cancer cell proliferation. Endoxifen Z-isomer offers a more effective alternative to tamoxifen in patients with poor CYP2D6 metabolism, which affects the conversion of tamoxifen to endoxifen. Its direct action on estrogen receptors provides enhanced efficacy, reducing the recurrence of breast cancer and offering a personalized approach to hormone therapy.

IC50 Avacopan, a selective C5a receptor inhibitor administered orally, gained approval in 2021 for treating adults with ANCA-associated vasculitis. In the pivotal phase 3 ADVOCATE trial involving patients with active granulomatosis with polyangiitis or microscopic polyangiitis, the avacopan group exhibited superior sustained remission rates at 52 weeks compared to the prednisone group.
