By constructing an in vivo-assembled, catalytically proficient peroxidase, C45, we have recently demonstrated the catalytic potential of simple, de novo-designed heme proteins. Here, we show that C45's enzymatic activity extends to the efficient and stereoselective intermolecular transfer of carbenes to olefins, heterocycles, aldehydes, and amines. Not only is this a report of carbene transferase activity in a completely de novo protein, but also of enzyme-catalyzed ring expansion of aromatic heterocycles via carbene transfer by any enzyme.

The object of the invention is to provide an excellent compound as a drug. The invention relates to a heterocyclic compound shown by the following formula: A-B-D-E [1] wherein A is heteroaryl or its oxide; B is ethenylene; D is optionally substituted phenylene; and E is a group of the formula: ?wherein G is optionally substituted phenyl; and R is heteroaryl or heteroarylmethyl, or a group of the formula: ?wherein n is an integer of 1 to 5; R5 and R6 are same or different and are independently selected from the group consisting of hydrogen, C1-C6 alkyl, hydroxyalkyl, aminoalkyl; or R5 and R6 taken together with the adjacent nitrogen atom may form 5- to 7-membered cyclic amino group for —NR5R6 or a salt thereof.
