Ovarian stimulation is an important step in the success rate of in vitro fertilization (IVF) allowing multiple follicular growth, several oocytes and consequently more embryos. The combination of GnRH-antagonists (GnRH-ant) and gonadotrophins is now available for clinical use and represent a valid alternative to classical protocol with GnRH agonist ...

mGluR5 antagonism inhibits cocaine reinforcement and relapse by elevation of extracellular glutamate in the nucleus accumbens via a CB1 receptor mechanism. [PDF]
Metabotropic glutamate receptor 5 (mGluR5) antagonism inhibits cocaine self-administration and reinstatement of drug-seeking behavior. However, the cellular and molecular mechanisms underlying this action are poorly understood.

Effect of the glucocorticoid receptor antagonist Org 34850 on fast and delayed feedback of corticosterone release [PDF]
We investigated the effect of the glucocorticoid receptor (GR) antagonist Org 34850 on fast and delayed inhibition of corticosterone secretion in response to the synthetic glucocorticoid methylprednisolone (MPL).

Interactions of narcotic antagonists and antagonist-analgesics
Abstract In the rat the potent narcotic antagonist N-cyclopropylmethyl-6,14-endoethano-7α- (1-hydroxy-1-methylethyl)-tetrahydronororipavine (M5050, Reckitt), which itself lacks analgesic activity, resembled naloxone in its capacity to reverse the antinociceptive effects of morphine antagonist-analgesics. The nociceptive stimulus employed

Antagonists to the rescue [PDF]
Errors in protein folding represent the underlying basis for a large number of genetically inherited diseases. Point mutations, deletions, and in some cases, expanded sequences of amino acids give rise to protein products that fail to reach their native folded state.

Chemokine G-protein coupled receptors are validated drug targets for many diseases, including cancer, neurological, and inflammatory disorders. Despite much time and effort spent on therapeutic development, very few chemokine receptor antagonists are ...

Structural modifications within the active site of the ACTH molecule have produced analogs that inhibit the hormone sensitive adenylate cyclase system of bovine adrenal cortical plasma membranes. It is demonstrated that the tryptophan residue of the ACTH molecule is essential for stimulation of the enzyme.

Adenosine-A2A Receptor Pathway in Cancer Immunotherapy
A2A receptors (A2AR), a typical GPCR with a high affinity for adenosine, was expressed in many immune cells, such as regulatory T cells, cytotoxic T cells, macrophages, etc.

Cannabinoid Receptor Involvement in Stress-Induced Cocaine Reinstatement: Potential Interaction with Noradrenergic Pathways [PDF]
This study examined the role of endocannabinoid signaling in stress-induced reinstatement of cocaine seeking and explored the interaction between noradrenergic and endocannabinergic systems in the process.
