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,正丁烷脱氢异构催剂可以分为两,金属双功能催剂金属氮、碳碳氧催剂。

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

苯达莫司汀，具有烷剂嘌呤似的双相功能可以在转移性乳腺癌（MBC）患者中发挥作用。
