were found to inhibitirreversibly both enzymes. Compound 10 was found to be a specific and selective inhibitor of human leukocyte elastase. In contrast to these, inhibitorsderivedfrom glycine methyl ester 1, D-valine methyl ester 4, and D-norvaline methyl ester 6 were found to be inactive. The results of the present study show that latent isocyanates derivedfrom appropriate aminoacids can serve as

1-(hydroxymethyl)-2,1-benzisoxazol-3(1H)-one which exhibited broad-spectrum antimicrobial and cytotoxic activity. A number of analogues were prepared by employing a modified zinc-reduction procedure on o-nitrobenzoate. Several of these analogues exhibited interesting antipseudomonal activity in agar and broth but were ineffective in vivo.
