Abstract:
The present invention relates to small molecule antagonists of Bcl-2 family proteins such as Bcl-2 and/or Bcl-XL. In particular, the present invention provides non-peptide cell permeable small molecules (e.g., tricyclo-dibenzo-diazocine-dioxides) that bind to a pocket in Bcl-2/Bcl-XL that block the anti-apoptotic function of these proteins in cancer cells and tumor tissues exhibiting Bcl-2 protein overexpression. In preferred embodiments, the small molecules of the present invention are active at the BH3 binding pocket of Bcl-2 family proteins (e.g., Bcl-2, Bcl-XL, and Mcl-1). The compositions and methods of the present invention are useful therapeutics for cancerous diseases either alone or in combination with chemotherapeutic or other drugs.
Abstract:
This invention relates to compositions comprising co-crystals of (−)-gossypol with a C1-8 carboxylic acid or C1-8 sulfonic acid which are useful as inhibitors of Bcl-2 family proteins. The invention also relates to the use of co-crystals of (−)-gossypol with a C1-8 carboxylic acid or C1-8 sulfonic acid for inducing apoptosis in cells and for sensitizing cells to the induction of apoptotic cell death.
Abstract:
The present invention relates to a class of compounds of formula (I) and (II): wherein R1 is hydrogen; linear or branched C1-C15 alkyl; C1-C15 alkenyl; C3-C6 cycloalkyl; mono, di, tri, tetra, penta substituted aryl or heteroaryl; COOR3; —(CH2)n-aryl; —COO—(CH2)nR3; —(CH2)n—COOR3; —C(O)R3; —C(O)NHR3; or an unsubstituted or substituted oxadiazole; and R2 is hydrogen; linear or branched C1-C15 alkyl; C1-C15 alkenyl; C3-C6 cycloalkyl; mono, di, tri, tetra, penta substituted aryl or heteroaryl; unsubstituted or substituted naphthyl; 1,3-Benzodioxole; fluorene; indole; isoquinoline; quinoline; pyridine; pyrimidine; onnthracene; or —(CH2)n-Ph; wherein the heteroaryl comprises N, O, or S, the mono or multi substituents on the aryl or heteroaryl are independently C1-C5 alkyl, C1-C5 alkenyl, H, F, Cl, Br, I, —NO2, NHR, or —OR, R is C1-C7 alkyl; R3 is C1-C5 alkyl, C1-C5 alkenyl, benzyl, substituted aryl or heteroaryl; and n=1-7. These compounds are discovered, synthesized and confirmed as potent inhibitors of dopamine (DA), serotonin (5-HT), and norepinephrine inhibitors. These compounds are therefore particularly useful in the treatment conditions or diseases wherein modulation of the monoamine neurotransmitter system involving dopamine (DA), serotonin (5-HT), and norepinephrine plays a role.
Abstract:
The invention relates to small molecules which function as inhibitors of anti-apoptotic Bcl-2 family member proteins (e.g., Bcl-2 and Bcl-xL). The invention also relates to the use of these compounds for inducing apoptotic cell death and sensitizing cells to the induction of apoptotic cell death.
Abstract:
The invention relates to diazo bicyclic Smac mimetics that are tethered through a covalent linker to give a bivalent species. Bivalent diazo bicyclic Smac mimetics function as inhibitors of Inhibitor of Apoptosis Proteins (IAPs). The invention also relates to the use of bivalent diazo bicyclic Smac mimetics for inducing or sensitizing cells to the induction of apoptotic cell death. Thus, compounds of the invention are useful in the treatment, amelioration, or prevention of hyperproliferative diseases such as cancer.
Abstract:
Potent and selective ligands for the dopamine 3 (D3) receptor are disclosed. The D3 receptor ligands have a structural formula (I) wherein X is C═O or SO2, R1 is C1-6 alkyl, R2 is aryl, heteroaryl, aryl, —(CH2)1-3aryl, or —(CH2)1-3heteroaryl, and n is 0 or 1. Methods of using the D3 receptor ligands in the treatment of diseases and conditions wherein modulation of the D3 receptor provides a benefit also are disclosed.
Abstract:
The invention relates to conformationally constrained mimetics of Smac which function as inhibitors of Inhibitor of Apoptosis Proteins. The invention also relates to the use of these mimetics for inducing apoptotic cell death and for sensitizing cells to inducers of apoptosis.
Abstract:
The invention relates to small molecules which function as inhibitors of the interaction between p53 and MDM2. The invention also relates to the use of these compounds for inhibiting cell growth, inducing cell death, inducing cell cycle arrest and/or sensitizing cells to additional agent(s).
