摘要:
This invention relates to compounds of formula (I): wherein Ring a, A, B, C, D, E, R and Q are defined herein. These compounds possess the ability to disrupt the interaction between regulatory proteins possessing one or more SH2 domains and their native ligands.
摘要:
Disclosed herein is a process for preparing (S)-.alpha.-amino-1-carboxycyclopentaneacetic acid which is a useful intermediate for preparing peptidomimetic inhibitors of herpes viral ribonucleotide reductase. The process comprises the preparation of the key intermediate ##STR1## and its subsequent conversion to the desired product.
摘要:
Disclosed herein are compounds of the formula ##STR1## in which Ar is phenyl or 1-naphthyl; R.sup.1 is hydrogen or lower alkyl; and R.sup.2 and R.sup.3 together with the nitrogen atom to which they are joined form a hyterocyclic amine radical selected from the group consisting of 1-pyrrolidinyl, piperidino, morpholino and 4-(lower alkyl)-1-piperazinyl. The compounds are antidepressant agents and methods for their preparation and use also are disclosed.

摘要:
Disclosed are compositions containing compounds of the formula (I) below wherein A,B,C,G,Q and R are defined herein. The compounds are useful as phosphotyrosine mimics that, when incorporated into an appropriate molecular structure, inhibit the binding of tyrosine kinase-dependent regulatory proteins to their native phosphotyrosine-containing ligands or receptors. Also disclosed are methods for preparing the compounds of the formula (I). ##STR1##

摘要:
Disclosed herein are compounds of the formula ##STR1## in which Ar is l-naphthyl; R.sup.1 and R.sup.2 are either the same or different selected from the group consisting of hydrogen or lower alkyl, or R.sup.1 and R.sup.2 together with the nitrogen atom to which they are joined form a heterocyclic amine radical selected from the group consisting of 1-pyrrolidinyl, piperidine, morpholine and 4-(lower alkyl)-1-piperazinyl; and R.sup.3 and R.sup.4 are either the same or different selected from the group consisting of hydrogen or lower alkyl, or R.sup.3 and R.sup.4 together with the nitrogen to which they are joined represent a heterocyclic amine radical selected from the group consisting of 1-pyrrolidinyl, piperidino, morpholino and 4-(lower alkyl)-1-piperazinyl; or a therapeutically acceptable acid addition salt thereof. The compounds are antidepressant agents and methods for their preparation and use also are disclosed.
