Wyeth-Ayerst Takes License to Develop Novel Gene Transcription
Modulators to Treat Diabetes

UNIONDALE, N.Y. Jan. 26 /PRNewswire/ -- OSI Pharmaceuticals, Inc.
(Nasdaq: OSIP) announced today that American Home Products Corporation
(NYSE: AHP) has exercised an option, under terms of a collaborative
research
agreement between OSI and American Home Products' Wyeth-Ayerst
Laboratories
division, to obtain an exclusive worldwide license to develop a series
of
novel, small molecule, gene transcription-based compounds that modulate
the
expression of phosphoenol pyruvate carboxy kinase, or PEPCK, a novel
target
for the treatment of non-insulin dependent diabetes mellitus, or Type II

diabetes.
Type II diabetes is a disorder of metabolism that results in
aberrant
regulation of blood glucose. Worldwide it is estimated that as many as
100 million people are afflicted by Type II diabetes, with an estimated
10 million patients in the U.S. Complications of the disease include
loss of
limbs, blindness, and kidney failure resulting from increased blood
glucose
levels and also cardiovascular disease resulting from atherosclerosis.
Reduction of blood glucose levels has been demonstrated to significantly

reduce the incidence of these complications. The small molecule,
transcription-based compounds derived from the OSI/Wyeth collaboration
effectively regulate blood glucose in a variety of animal models by
modulating
the expression of PEPCK.
"We believe that Wyeth's decision to take the license represents a
further
validation of our novel, patented approach targeting the modulation of
gene
transcription," stated Gary E. Frashier, Chief Executive Officer of OSI
Pharmaceuticals. "Continued development of the compounds targeting
PEPCK for
the treatment of Type II diabetes may result in effective new therapies
for
this chronic, often devastating disease."
"We are pleased with this positive outcome of the collaboration
between
OSI and Wyeth," stated Richard L. Jackson, Ph.D., Senior Vice President,

Discovery Research, Wyeth-Ayerst Research. "We look forward to the
successful
development of one or more of the compounds that have emerged from the
collaboration, which could result in a clinical development candidate in
the
next 12 to 18 months."

Abstract:
The present invention provides a method of transcriptionally
modulating the expression of a gene-of-interest. The method
comprises contacting a cell which is capable of expressing the gene
with an amount of a molecule effective to transcriptionally modulate
expression of the gene and thereby affect the level of the protein
encoded by the gene which is expressed by the cell. Molecules
useful in the practice of the invention are characterized as follows (a)
do not naturally occur in the cell, (b) bind to DNA or RNA or bind to a
protein through a domain of such protein which is not a ligand binding
domain of a receptor which naturally occurs in the cell. Additionally,
this invention provides a method for determining whether a molecule
known to be a modulator of protein biosynthesis is capable of
transcriptionally modulating expression of a gene-of-interest.


First Claim:

What is claimed is:
1. A method of determining whether a chemical not previously known to be a modulator of protein
biosynthesis specifically transcriptionally modulates the expression of a gene-of-interest which
comprises:

(a) contacting a sample which contains a predefined number of identical eucaryotic cells with a
predetermined concentration of the chemical to be tested, each comprising a single DNA
construct consisting essentially of in 5' to 3' order
(i) a modulatable transcriptional regulatory sequence of the gene-of-interest,
(ii) a promoter of the gene-of-interest, and
(iii) a reporter gene which expresses a polypeptide that produces a detectable signal,
coupled to, and under the control of, the promoter, under conditions wherein the chemical
if capable of acting as a transcriptional modulator of the gene-of-interest, causes a
detectable signal to be produced by the polypeptide expressed by the reporter gene;
(b) quantitatively determining the amount of the signal produced in (a);
(c) comparing the amount of signal determined in (b) with the amount of signal produced and
detected in the absence of any chemical being tested and with the amount of signal produced
and detected upon contacting the sample in (a) with other chemicals, thereby identifying the test
chemical as a chemical which causes a change in the amount of detectable signal produced by
the polypeptide expressed by the reporter gene, and thereby determining whether the test
chemical specifically transcriptionally modulates expression of the gene-of-interest.
