An object of the present invention is to provide a photocuring method, which makes it possible to rapidly and efficiently obtain a crosslinked product (resin), a compound used in the photocuring method, and a photocuring resin composition containing the compound. The present invention relates to a photocuring method, which comprises a step 1 and a step 2 performed after the step 1, a compound used in the photocuring method, and a photocuring resin composition containing the compound. Step 1: this is a step in which in the presence of (A) compound having a carbonyl group generating a radical by photoirradiation and a carboxyl group decarboxylated by photoirradiation, (B) silane coupling agent having a mercapto group or a (meth)acryl group is reacted with (C) water under acidic conditions to obtain (D) silane compound having a mercapto group or a (meth)acryl group and at least one silanol group. Step 2: this is a step in which in the presence of the compound (A) and (E) compound having a carbonyl group generating a radical by photoirradiation and a group generating a base by being decarboxylated by photoirradiation, the compound (A) and the compound (E) are irradiated with light to create alkaline conditions in a reaction system by decarboxylating the carboxyl group of the compound (A) and generating a base from the compound (E), and radicals are generated from the compound (A) and the compound (E) to generate a crosslinked product containing a constitutional unit derived from the silane compound (D) from the silane compound (D) and, if necessary, from (F) compound having two or more polymerizable unsaturated groups.

Rhein analogues that exhibit anti-proliferative activity, particular against cancer cells, are described herein. In some embodiments, the compounds contain a flat or planar ring system. Such rings system by facilitate non-covalent binding of the compounds to the DNA complex, such as by intercalation. In some embodiment, the compounds contain a flat or planar ring system as described above and one or more substituents which are alkylating moieties, electrophilic groups or Michael acceptors or groups which contain one or more alkylating moieties, electrophilic groups and/or Michael acceptors. The compounds described herein can also contain one more functional groups to improve the solubility of the compounds.
