Keywords: PI3K inhibitor thienopyrimidine thiazolopyrimidine synthesis anticancer; Anti-tumor activities; Fraction of sp(3) carbon atoms (Fsp(3)); Phosphoinositide 3-kinase inhibitors; Thiazolo[5,4-d]pyrimidine; Thieno[2,3-d]pyrimidine.They researched the compound: 4-Methoxypiperidine( cas:4045-24-3 ).Product Details of 4045-24-3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:4045-24-3) here.
As abnormal PI3K signaling is a feature of many types of cancer, the development of orally active PI3K inhibitors is of great significance for targeted cancer therapy. Through integrating strategies of reducing aromatic character/increasing the fraction of sp3 carbons together with scaffold hopping, we designed and synthesized two new series of thieno[2,3-d]pyrimidine and thiazolo[5,4-d]pyrimidine derivatives for use as PI3K inhibitors. Our structure-activity relationship studies led to the identification of thieno[2,3-d]pyrimidine 6a and thiazolo[5,4-d]pyrimidine 7a (I and II, resp.), which exhibited remarkable nanomolar PI3K potency, good antiproliferative activity, favorable pharmacokinetic properties and significant in vivo anti-cancer efficacy. Notably, thiazolo[5,4-d]pyrimidine 7a had better anti-cancer activity than thieno[2,3-d]pyrimidine 6a and is worthy of further pre-clin. evaluation for its use in cancer treatment.
