The present invention relates generally to the field of anti-cancer therapy. More particularly, it provides novel crystalline forms of organic arsenic compounds and methods for their use in treating cancers such as leukemia and solid tumors. Specifically, a crystalline form of darinaparsin, wherein the crystalline form has a melting point in the range of about 190-200 deg C.
本发明通常涉及抗癌治疗领域。更具体地说,它提供了有机
砷化合物的新颖晶体形式及其在治疗白血病和实体肿瘤等癌症方面的应用方法。具体而言,是一种达利那巴星的晶体形式,其中晶体形式的熔点在约190-200摄氏度的范围内。
