    摘要: Psoralen compounds are synthesized which have substitutions on the 4, 4', 5', and 8 positions of the psoralen, which permit enhanced binding to nucleic add of pathogens. Higher psoralen binding levels and lower mutagenicity are described, resulting in safer, more efficient, and reliable inactivation of pathogens in blood products. The invention contemplates inactivation methods using the new psoralens which do not compromise the function of blood products for transfusion. In particular compounds with primary aminoalkyl substitutions on the 4' or 5' positions of psoralen are used to inactivate pathogens in blood products such as platelets.

    摘要: Pilocarpine analogues are provided having the structure ##STR1## where one of R.sub.1 or R.sub.2 is an alkyl, such as methyl, ethyl, propyl, butyl, and so forth, and the corresponding secondary alkyl groups, an aralkyl, such as benzyl, phenylethyl, phenylpropyl, and the corresponding secondary aralkyl residues, or a cycloalkyl having less than about 12 carbon atoms. R.sub.3 has at least two carbon atoms but less than about 9. These pilocarpine analogues have improved duration of biological activity with respect to pilocarpine. A particularly preferred compound is a muscarinic agonist equipotent with pilocarpine, where R.sub.2 is methyl, and R.sub.3 is ethyl.

    摘要: An optically active alpha-amino acid derivative having the formula: ##STR1## wherein: X is OH, Cl, Br, I, or OCOR.sub.3 ;Y is a radical selected to stabilize the alpha carbon atom of the alpha-amino acid derivative sufficiently to prevent significant change in symmetry thereof during replacement of X with an alkyl, aryl, alkenyl, alkynyl, alkaryl, aralkyl, alkenaryl or alkynaryl radical, or such radical having one or more chemical constituents thereon; andR.sub.1 and R.sub.2 are different from one another and are each hydrogen or an alkyl, aryl, alkenyl, alkynyl, alkaryl, aralkyl, alkenaryl, or alkynaryl radical, or such radical having one or more non-protic chemical constituents thereon is conventionally synthesized from the corresponding alpha-amino acid. The ##STR2## portion of the above derivative is converted to a ketone functionality without racemization.
