The invention relates to methods of sonodynamic therapy comprising the co-administration of a microbubble-chemotherapeutic agent complex together with a microbubble-sonosensitiser complex. It further relates to pharmaceutical compositions comprising these complexes and their use in methods of sonodynamic therapy and/or sonodynamic diagnosis. Such methods find particular use in the treatment of cancer, e.g. pancreatic cancer.

text] The inhibitor of type 1 17beta-hydroxysteroid dehydrogenase EM-1745 (1) exhibits affinity for both the substrate (estrone or estradiol) and the cofactor (NAD(P)H) binding domains. However, to increase its bioavailability, this compound needs to be simplified. The efficient and convergent synthesis of simplified substrate/cofactor hybrid inhibitors (compounds 2) involving a cross-metathesis and a

A highly regioselective Pd-catalyzed carboxyl directed decarboxylative ortho-C–H halogenation of cheap o-nitrobenzoic acids with NaX (X = I, Br) under aerobic conditions has been established. The utility of the method has been demonstrated by the gram-scale reaction and derivatization of the product. Experimental results have confirmed Pd and Bi played critical roles in the transformation and indicated
