Cayman Adjudin

Adjudin is a derivative of ionidamine that inhibits human spermatozoa capacitance, potentially by blocking chloride channels.¹ It inhibits spermatozoa hyperactivated motility and the acrosome reaction and prevents sperm-egg fusion in zona-free hamster eggs. It also disrupts Sertoli-germ cell junctions by increasing tight junction and basal ectoplasmic specialization protein levels, which tightens the cell permeability barrier dose-dependently in vitro.² Adjudin (25 and 50 mg/kg) increases testin expression in adult rat testes within one day and depletes spermatids and spermatocytes within 14 days.³ Under various dosing parameters, adjudin reversibly induces infertility of male rats within 3-7 weeks, which lasts 4-14 weeks, without affecting serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), or testosterone. Adjudin also decreases proliferation of SGC-7901, MDA-MB-231, Smmc-7721, and MIA Paca-2 cells (IC₅₀s = 58, 13.8, 72.3, and 52.7 µM, respectively) and induces apoptosis via the caspase-3-dependent pathway.⁴
