Oxadiazoline Ligands For Modulating The Expression Of Exogenous Genes Via An Ecdysone Receptor Complex

View page
US Patent:
7304162, Dec 4, 2007
Filed:
Feb 19, 2004
Appl. No.:
10/783810
Inventors:
Robert Eugene Hormann - Melrose Park PA, US
Orestes Chortyk - Thompson Station TN, US
Dat Phat Le - North Wales PA, US
Assignee:
Intrexon Corporation - Blacksburg VA
International Classification:
A61K 31/4245
C07D 271/07
A61K 31/433
C07D 285/08
US Classification:
548133, 514361, 514364, 514128
Abstract:
The present invention relates to non-steroidal ligands for use in nuclear receptor-based inducible gene expression system, and a method to modulate exogenous gene expression in which an ecdysone receptor complex comprising: a DNA binding domain; a ligand binding domain; a transactivation domain; and a ligand is contacted with a DNA construct comprising: the exogenous gene and a response element; wherein the exogenous gene is under the control of the response element and binding of the DNA binding domain to the response element in the presence of the ligand results in activation or suppression of the gene.

US Patent:
20010044151, Nov 22, 2001
Filed:
Apr 12, 2001
Appl. No.:
09/832500
Inventors:
Glenn Carlson - North Wales PA, US
Dean Cress - Souderton PA, US
Tarlochan Dhadialla - Chalfont PA, US
Robert Hormann - Philadelphia PA, US
Dat Le - North Wales PA, US
International Classification:
C12N015/82
A61K031/16
A61K048/00
US Classification:
435/468000, 514/044000, 514/615000
Abstract:
This invention relates to an improved method to modulate exogenous gene expression in which an ecdysone receptor complex comprising: a DNA binding domain; a ligand binding domain; a transactivation domain; and a ligand is contacted with a DNA construct comprising: the exogenous gene and a response element; wherein the exogenous gene is under the control of the response element and binding of the DNA binding domain to the response element in the presence of the ligand results in activation or suppression of the gene. The improvement resides in a select group of non-steroid ligands which show improved activity over known ligands.
