ABSTRACT
|
|
|
|
| |
|
|
High-throughput screening of the P&GP corporate repository against several
protein tyrosine phosphatases identified the sulfamic acid moiety as potential
phosphotyrosine mimetic. Incorporation of the sulfamic acid onto a
1,2,3,4-tetrahydroisoquinoline scaffold provided a promising starting point for
PTP1B inhibitor design.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
