Cancer is one of the major causes of death worldwide. Although many advances have been made in the treatment and management of the disease, the existence of chemotherapy-resistance means there is still a great need to develop new strategies and drugs for its treatment. Provided herein are synthetic derivatives of combretastatin A-4, in particular those in which the aromatic rings are locked into a non-isomerisable active conformation, thus resulting in improved, stable compounds. The novel compounds are structurally related to combretastatin A-4 (CA-4) and lock the rings into the known active conformation by means of a four membered nitrogen containing heterocyclic ring, such as a beta-lactam ring, incorporated into the standard CA-4 structure. The compounds exhibit potent anti-cancer activity.
癌症是全球主要的死因之一。尽管在治疗和管理该疾病方面取得了许多进展,但化疗耐药的存在意味着仍然需要开发新的策略和药物来治疗癌症。本文提供了合成的血树碱A-4的衍
生物,特别是那些将芳香环锁定在非可异构的活性构象中,从而产生改进的、稳定的化合物。这些新型化合物与血树碱A-4(
CA-4)有结构上的关联,并通过一种四元杂环环(例如β-内酰胺环)将环锁定在已知的活性构象中。这些化合物表现出强大的抗癌活性。
