The invention provides a method of preparing a microbubble covalently attached to at least one therapeutic agent which comprises: (i) providing a lipid (e.g. a phospholipid) capable of forming a microbubble; covalently linking at least one therapeutic agent to said lipid to produce a functionalised lipid; and preparing a microbubble from said functionalised lipid. Microbubble-therapeutic agent complexes which comprise a microbubble shell formed from a plurality of lipids (e.g. phospholipids) in which at least a proportion of the lipids are covalently linked to at least one therapeutic agent are also provided. Examples of therapeutic agents which may be attached to the microbubble include chemotherapeutic agents and sonosensitising agents. The complexes find use in methods of sonodynamic therapy and, in particular, in methods of combined sonodynamic therapy and chemotherapy.
该发明提供了一种制备与至少一种治疗剂共价连接的微泡的方法,该方法包括:提供一种能够形成微泡的脂质(例如磷脂);将至少一种治疗剂共价连接到所述脂质以产生功能化脂质;以及从所述功能化脂质制备微泡。还提供了包含由多个脂质(例如磷脂)形成的微泡壳的微泡-治疗剂复合物,其中至少一部分脂质共价连接到至少一种治疗剂。可能连接到微泡的治疗剂的例子包括化疗药物和声敏化剂。这些复合物在声动力治疗方法中找到了用途,特别是在结合声动力治疗和化疗的方法中。
