PTC299 是 VEGFA mRNA 翻译的抑制剂，在转录后水平选择性地抑制 VEGF 蛋白的合成。PTC299 也是二氢乳酸盐脱氢酶 (DHODH) 的有效抑制剂。PTC299 良好的口服生物利用度，缺乏脱靶激酶抑制和骨髓抑制。PTC299 可用于血液系统恶性肿瘤的研究。 PTC299 is active inhibitor of VEGFA mRNA translation that selectively inhibits VEGF protein synthesis at the post-transcriptional level. PTC299 is also a potent inhibitor of dihydroorotate dehydrogenase (DHODH). PTC299 shows good oral bioavailability and lack of off-target kinase inhibition and myelosuppression. PTC299 can be useful for the research of hematologic malignancies.
