Trapping reactions in singlet oxygenation of 2-phenylindole (1) and nucleophilic addition reactions of 2-phenyl-3H-indol-3-one (4) both in methanolic media were studied comparatively.

AIM: To evaluate the effect of 4-6-diamidino-2-phenylindole (DAPI) as fluorescent tracer during the epidermal grafting, and establish the basis of cellular proliferation and differentiation research.
