Melanogenesis from topical mechlorethamine and analogues in skin of hairless mice and in vitiligo.
Progressive repigmentation occurred in vitiliginous skin of two patients topically treated with aqueous solutions of mechlorethamine. Hairless mice were found to provide what seems to be a satisfactory cutaneous system for evaluating potential melanogenic properties of topically applied test compounds.

Pigment production of Cryptococcus neoformans grown with extracts of Guizotia abyssinica.
Brown pigment(s) formed in Cryptococcus neoformans when grown on media containing extracts of the seeds of Guizotia abyssinica cannot be extracted by common organic solvents or by 6 n HCl or 2 n NaOH. A similar pigmentation was observed in C. neoformans when grown on a medium containing caffeic acid isolated from the hydrolyzed methanol extract of G. abyssinica seeds. Its methyl ester and the diacetate thereof, as well as the following structurally related compounds, 3-hydroxytyramine, 3,4-dihydroxybenzoic acid, 3,4-dihydroxyphenylethanolamine, and 4-hydroxy-3,5-dimethoxycinnamic acid, brought about similar pigmentation. However, 2,4-, 2,5-, 2,6-, and 3,5-dihydroxybenzoic acids, tyrosine, phenylalanine, cinnamic acid, 4-hydroxycinnamic acid, and 4-hydroxy-3-methoxycinnamic acid did not cause coloration in C. neoformans.
