The present invention relates to a method of treating a hyperproliferative disorder comprising administering a ceramide generating retinoid comprising a retinoic acid derivative or a pharmaceutically acceptable salt thereof, and D-threo-PPMP as a ceramide degradation inhibitor or a pharmaceutically acceptable salt thereof, wherein the hyperproliferative disorder is a tumor; and wherein the ceramide generating retinoid is administered in an amount effective to produce necrosis, apoptosis or both in the tumor, and the ceramide degradation inhibitor is administered in an amount effective to increase the necrosis, apoptosis or both in the tumor over that expected to be produced by the sum of that produced by the ceramide generating retinoid and the ceramide degradation inhibitor when administered separately.
本发明涉及一种治疗高增殖疾病的方法,包括给予一种含有维甲酸衍生物或其药用盐的鞘氨醇生成型视黄醇,并给予 D-左右旋-PPMP 作为一种鞘氨醇降解抑制剂或其药用盐,其中高增殖疾病是肿瘤;所述鞘氨醇生成型视黄醇以有效剂量给予以在肿瘤中产生坏死、凋亡或两者,且所述鞘氨醇降解抑制剂以有效剂量给予以增加肿瘤中的坏死、凋亡或两者,使其超过单独给予鞘氨醇生成型视黄醇和鞘氨醇降解抑制剂所产生的效果之和。
