GLPG1690(Ziritaxestat)는 IC50 131nM, Ki 15nM를 가지는 새로운 자세크리트 운동인자(ATX) 억제제이다. 이것은 특이성 폐섬유화의 진행을 효과적으로 멈추고 있다.
GLPG1690(20nM; 68-96시간)은 ATX가 상승 조절되는 TSC2 결핍 세포의 증식을 억제한다. 또한 GLPG1690은 TSC2 결핍 세포의 이동과 댐핑 없이 자라는 성장을 억제한다[3].
GLPG1690(구강 투여; 50 또는 100 mg/kg; 12시간마다 19일간)은 쥐의 혈장에서ATX활성과 녹색 인산(LPA) 농도를 낮추었다. 또한 GLPG1690은 방사선치료와 결합하여 쥐 내에서 암세포 증식의 억제를 강화한다[4]. GLPG1690은 쥐에서 녹색 인산화 콜린(LPC)으로 인한 내피 기능 장애를 반전시켰다[5].
