A Three-Symbol Code for Searching Chemical Structures

Multi-Level Retrieval Systems. III. A Generic Chemical Search System Using Optical Coincidence Cards

“…These cards show the following layouts: cc [1][2][3][4][5][6][7][8][9][10][11][12] Fragment Codes (Card 2). Fragment codes relating to the functional groups that are generally found in the Warner-Lambert compound collection are entered, one code per card, in cc 16-21 of Card 2 and are designed to offer increasing levels of either genericity or specificity, as may be desired in a given search.…”

A Correlative Indexing and Retrieval System for the Screening of Biological Data.

“…The result of such a search provides biological models that are used to define search parameters for our chemical retrieval system. 1 The compounds recovered then will indicate the untested substances that should be scheduled for screening or evaluation, and suggest possible directions of synthesis by showing activity changes versus chemical type. An example of such a multiple correlative search might be the following:…”
