Background : Bendamustine, a bifunctional alkylating agent with anticipated purin-like properties is active in metastatic breast cancer (MBC) patients.

苯达莫司汀，具有烷化剂和嘌呤类似的双相功能可以在转移（MBC）发挥作用。

The catalysts on studying can divide into two kinds: the transition metal bifunctional catalysts and the nitride, carbide and oxycarbide catalysts of transition metals.

目前,正丁烷脱氢异构催化剂可以分为两类,过渡金属双功能催化剂和过渡金属氮化物、碳化物和碳氧化物催化剂。
