Abstract: This invention provides a process for preparing acylaromatics comprising reacting an aromatic compound with a carboxylic acid in the presence of a reaction medium comprising polyphosphoric acid and a strong protic acid. In one embodiment, the invention provides a process for preparing a para-acyl phenoxyethylamine comprising the steps of reacting a 2-phenoxyethyl compound bearing a leaving group on the ethyl 1-position with a carboxylic acid in the presence of a reaction medium comprising polyphosphoric acid and a strong protic acid, to form apara-acyl phenoxyethyl intermediate bearing the leaving group; and reacting the para-acyl phenoxyethyl intermediate with an amine that substitutes for the leaving group to form the para-acyl phenoxyethylamine.

Abstract: The present invention discloses synthetic peptides and antibodies raised thereto wherein the synthetic peptides represent important epitopic sites recognized by the 0.5 .alpha. antibody, a human monoclonal antibody which can neutralize HTLV-I. Also, the uses of these peptides or antibodies thereto either alone or in combination with peptides representing the epitopic site for the predominant antibodies found in HTLV-I env seropositive sera as diagnostics, therapeutics and vaccines are disclosed.

Abstract: The mRNA coded by the "anti-sense" strand of the complementary DNA produced by HTLV-I infection contains significant open reading frames. Cells infected by HTLV-I virus produce mRNA that is anti-sense to the viral RNA genome. Infected cells may produce proteins from the newly discovered mRNA. The production of the anti-sense in mRNA initiates from a newly discovered transcriptional promoter located within 1.8 kb from the 3' terminus of the viral genome. The mRNA, protein, and antibodies directed thereto can be used in the prevention, diagnosis, and treatment of HTLV-I infections.
