Cenerimod is an investigational new drug that is being evaluated for the treatment of systemic lupus erythematosus. [1] It is a sphingosine-1-phosphate receptor modulator. [2]
Racetams are a class of drugs that share a pyrrolidone nucleus. Some, such as piracetam, aniracetam, oxiracetam, pramiracetam and phenylpiracetam are considered nootropics. Others such as levetiracetam, brivaracetam, and seletracetam are anticonvulsants.
LY-404187 is an AMPA receptor positive allosteric modulator which was developed by Eli Lilly and Company. It is a member of the biarylpropylsulfonamide class of AMPA receptor potentiators.
BMS-564,929 is an investigational selective androgen receptor modulator (SARM) which is being developed by Bristol-Myers Squibb for treatment of the symptoms of age-related decline in androgen levels in men ("andropause"). These symptoms may include depression, loss of muscle mass and strength, reduction in libido and osteoporosis. Treatment with exogenous testosterone is effective in counteracting these symptoms but is associated with a range of side effects, the most serious of which is enlargement of the prostate gland, which can lead to benign prostatic hypertrophy and even prostate cancer. This means there is a clinical need for selective androgen receptor modulators, which produce anabolic effects in some tissues such as muscle and bone, but without stimulating androgen receptors in the prostate.
LGD-2226 is an investigational selective androgen receptor modulator (SARM), which is being developed for treatment of muscle wasting and osteoporosis.
Andarine is a selective androgen receptor modulator (SARM) which was developed by GTX, Inc for the treatment of conditions such as muscle wasting, osteoporosis, and benign prostatic hypertrophy (BPH), using the nonsteroidal antiandrogen bicalutamide as a lead compound. Development of andarine for all indications has been discontinued, in favor of the structurally related and improved compound enobosarm.
AC-262536 is a drug developed by Acadia Pharmaceuticals which acts as a selective androgen receptor modulator (SARM). Chemically it possesses endo-exo isomerism, with the endo form being the active form. It acts as a partial agonist for the androgen receptor with a Ki of 5 nM, and no significant affinity for any other receptors tested. In animal studies it produced a maximal effect of around 66% of the levator ani muscle weight increase of testosterone, but only around 27% of its maximal effect on prostate gland weight. It is an aniline SARM related to ACP-105 and vosilasarm (RAD140).
In pharmacology and biochemistry, allosteric modulators are a group of substances that bind to a receptor to change that receptor's response to stimuli. Some of them, like benzodiazepines or alcohol, function as psychoactive drugs. The site that an allosteric modulator binds to is not the same one to which an endogenous agonist of the receptor would bind. Modulators and agonists can both be called receptor ligands.
PNU-120596 is a drug that acts as a potent and selective positive allosteric modulator for the α7 subtype of neural nicotinic acetylcholine receptors. It is used in scientific research into cholinergic regulation of dopamine and glutamate release in the brain.
Pregnenolone sulfate is an endogenous excitatory neurosteroid that is synthesized from pregnenolone. It is known to have cognitive and memory-enhancing, antidepressant, anxiogenic, and proconvulsant effects.
S-18986 is a positive allosteric modulator of the AMPA receptor related to cyclothiazide. It has nootropic and neuroprotective effects in animal studies, and induces both production of BDNF and AMPA-mediated release of noradrenaline and acetylcholine in the hippocampus and frontal cortex of the brain.
A serotonin modulator and stimulator (SMS), sometimes referred to more simply as a serotonin modulator, is a type of drug with a multimodal action specific to the serotonin neurotransmitter system. To be precise, SMSs simultaneously modulate one or more serotonin receptors and inhibit the reuptake of serotonin. The term was created to describe the mechanism of action of the serotonergic antidepressant vortioxetine, which acts as a serotonin reuptake inhibitor (SRI), agonist of the 5-HT1A receptor, and antagonist of the 5-HT3 and 5-HT7 receptors. However, it can also technically be applied to vilazodone, which is an antidepressant as well and acts as an SRI and 5-HT1A receptor partial agonist.
A receptor modulator, or receptor ligand, is a general term for a substance, endogenous or exogenous, that binds to and regulates the activity of chemical receptors. They are ligands that can act on different parts of receptors and regulate activity in a positive, negative, or neutral direction with varying degrees of efficacy. Categories of these modulators include receptor agonists and receptor antagonists, as well as receptor partial agonists, inverse agonists, orthosteric modulators, and allosteric modulators, Examples of receptor modulators in modern medicine include CFTR modulators, selective androgen receptor modulators (SARMs), and muscarinic ACh receptor modulators.
A channel modulator, or ion channel modulator, is a type of drug which modulates ion channels. They include channel blockers and channel openers.
An enzyme modulator is a type of drug which modulates enzymes. They include enzyme inhibitors and enzyme inducers. In an homogeneous assay, "an enzyme modulator ... is covalently linked to the ligand which competes with free ligand from the test sample for the available antibodies."
Vosilasarm, also known by the development codes RAD140 and EP0062 and by the black-market name Testolone or Testalone, is a selective androgen receptor modulator (SARM) which is under development for the treatment of hormone-sensitive breast cancer. It is specifically under development for the treatment of androgen receptor-positive, estrogen receptor-negative, HER2-negative advanced breast cancer. Vosilasarm was also previously under development for the treatment of sarcopenia, osteoporosis, and weight loss due to cancer cachexia, but development for these indications was discontinued. The drug is taken by mouth.
Asoprisnil ecamate (INN) is a synthetic, steroidal selective progesterone receptor modulator (SPRM) which was under development for the treatment of endometriosis, uterine fibroids, and menopausal symptoms but was discontinued. It is a potent and highly selective ligand of the progesterone receptor with mixed agonistic and antagonistic activity and much reduced antiglucocorticoid activity relative to mifepristone. The drug reached phase III clinical trials for the aforementioned indications prior to its discontinuation.
NC 45-0095 is a synthetic nonsteroidal selective estrogen receptor modulator (SERM) which was under development by Novo Nordisk for the treatment of postmenopausal osteoporosis but was never marketed. It is a partial agonist of the estrogen receptor (IC50Tooltip half-maximal inhibitory concentration (for binding inhibition) = 9.5 nM; EC50Tooltip half-maximal effective concentration = 13 nM) with mixed estrogenic and antiestrogenic activity, and shows full estrogenic activity in bone and uterus (EmaxTooltip maximal efficacy (relative to moxestrol, in Ishikawa endometrial cancer cell line) = 105%). The compound is a pyrroloindolizine derivative. Its development was discontinued by 2003.
OPK-88004 is a non-steroidal indole derivative which acts as a selective androgen receptor modulator (SARM). It has been investigated by OPKO Health for the treatment of erectile dysfunction and symptoms associated with benign prostate hyperplasia.
GLPG-0492 (DT-200) is a drug which acts as a selective androgen receptor modulator (SARM). It has been investigated for the treatment of cachexia and muscular dystrophy.
ACP-105 is a drug which acts as a selective androgen receptor modulator (SARM). It has been investigated for potential use in the treatment of age-related cognitive decline. The drug has been found to reduce anxiety-like behavior in a mouse model of Alzheimer's disease when administered alone, as well as enhance spatial memory when coadministered with the selective estrogen receptor β agonist AC-186. ACP-105 is an aniline SARM and is related to AC-262536 and vosilasarm (RAD140).
