Abstract: Methods for the synthesis of arginine-containing peptides are provided. The methods include a deprotection step that minimizes the transfer of by-products deriving from cleaved sulfonyl-5 based side chain protecting groups from arginine to amino acids carrying electron rich side chains.

Abstract: Novel biaromatic compounds, which are vitamin D analogs, processes for their preparation and cosmetic, dermatological and pharmaceutical preparations containing one or more of these compounds.

Abstract: The present invention relates to a novel composition comprising danielone and derivatives thereof as well as to the use of such compositions in skin lightening. More particularly, the present invention relates to danielone and derivatives thereof for use in topical compositions for smoothening skin color irregularities, for reducing melanin formation in the human skin, for lightening/brightening human skin and/or for treatment of pigmentation disorders which comprises topically administering an effective amount of danielone and derivatives thereof to the appropriate skin area of a person in need of such beautifying agent, or treatment.
