[相關申請]
本申請主張2021年11月2日提交的美國臨時申請案第63/274,596號與2022年6月1日提交的美國臨時申請案第63/347,671號的優先權,其全部內容藉由引用併入本文。
本揭示係關於一種PPARG反向促效劑及其用途。
PPARγ(PPARG)係一種II型配體依賴性核激素受體(屬於PPAR核受體亞家族),與類視黃醇X受體(RXRs)形成專性異二聚體。PPARG主要在脂肪組織、結腸、巨噬細胞與尿路上皮的管腔層中表現。PPARG被稱為脂肪生成的主要調節劑,可調節脂肪細胞分化、脂肪酸儲存與葡萄糖代謝。PPARG還被證明在巨噬細胞的代謝與炎症中發揮重要作用,其由IL4誘導並控制麩醯胺酸代謝。在正常的尿路上皮中,PPARG對其體內平衡與再生至關重要。
PPARG在癌症中的作用最初係從基因組研究中推斷出來,該研究確定了濾泡性甲狀腺癌中的PAX8-PPARG染色體的重排。最近,已發現PPARG在尿路上皮癌的管腔亞型中過度表現與基因改變。這與長期使用PPARG促效劑與尿路上皮癌發病率增加有關的報導一致。大多數尿路
上皮癌係尿路上皮癌(urothelial carcinoma),係分為非肌肉浸潤性尿路上皮癌(NMIUC,70%)、肌肉浸潤性尿路上皮癌(MIUC,25%)或轉移性尿路上皮癌(MUC,5%)。MIUC通常係從頭診斷,但可能有10%到20%的NMIUC病例最終進展。MIUC係一種異質性和侵襲性疾病,局部疾病患者的五年生存率為60%,遠處轉移患者的五年生存率低於10%。對NMIUC與MIUC的分子認識有了顯著提高,包括分子亞型與尿路上皮分化之間的關聯。已經提出了幾種MIUC分子類別,其中激活的PPARG特徵在管腔亞型中具有顯著特徵。一線治療係化療,在不適合化療或二線之情況下有多種選擇,但治療選擇有限,且總生存率低。
需要開發有效的PPARG調節劑來治療癌症,例如NMIUC、MIUC和MUC,以及相關病症。
