Talazoparib tosylate (BMN 673ts)는 강력하고 구강 내 복용 가능한 PARP1/2 억제제로Talazoparib의 토시롤레이트 형태이다. Talazoparib는 PARP1을 억제하는IC50값이 0.57nM이다. PARP1은 단일 가닥 끊김을 수리하는 데 중요한 DNA 수리효소이다[2]. Talazoparib는 선택적 항종암활성성을 가지고 있다[3].

체외 실험에서 Talazoparib(0.1-100nM)로 72시간 처리한 Brca1−/− BR5FVB1-Akt 세포는 용량에 따라 세포 증식을 억제하는 방식으로 작용하였다[4]. DT40와 DU145 세포에 대해 72시간 Talazoparib 처리는 각각 4nM와 11nM의 IC50 값을 가지며 상당한 세포 독성 효과를 보였다[5]. Talazoparib 처리를 받은 네 가지 인간의 머리와 목 암 세포 계통(UMSCC-5, -6, -12, -38)은 세포 성장에 상대적으로 억제 효과를 보였으며 IC50 범위가 0.1-10μM 범위로 나타났다[6].

체내 실험에서 Talazoparib(0.33mg/kg)로 구강 치료를 받은 MX-1 종양 이종 이식을 가진 쥐는 종양 성장을 현저하게 억제하고, 종양 세포 내의 ADP-리보즈(PAR) 수준을 낮추었다[7].
