The present invention provides a computer-assisted method of generating a protonophore requiring the use of a computer including a processor. The method includes: designing the protonophore, calculating, using the processor, an estimated protonophoric activity; producing the protonophore if the estimated protonophoric activity corresponds to an U
50
of about 20 μM or less; and determining the uncoupling activity of the protonophore. The present invention also provides novel protonophores that meet the above requirement and their methods of use.

of the novel 3H,3'H‐spiro[benzofuran‐2,2'‐benzo[b]thiophene]‐3,3'‐dione skeleton was realized from the reaction of (Z)‐3‐hydroxy‐1‐(2‐hydroxyphenyl)‐3‐(2‐halogenphenyl)prop‐2‐en‐1‐ones with potassium ethylxanthate in the presence of 1,10‐phen. The reaction sequence was postulated to encompass a PIDA‐mediated oxidative C–O bond formation followed by a CuBr‐mediated spirocyclization step.

at least one aurone or a natural or synthetic derivative of aurone, or an analogue of aurone, in which the independent phenyl ring can be substituted by a heterocycle of pyrrole, imidazole, triazole, pyridine, furan, or thiophene type, is disclosed as a cosmetic agent, or as an active substance, for the manufacture either of a cosmetic composition, or of a pharmaceutical composition, notably a dermatological composition, having a melanogenesis-inhibiting activity or a depigmenting activity, or an anti-tyrosinase activity.
