Benzylamine

Benzylamine consists of a benzyl group attached to an amine functional group. This colorless liquid is a common precursor in organic synthesis. It is used as a masked source of ammonia, since after N-alkylation, the benzyl group can be removed by hydrogenolysis.

Properties Suppliers
Bepotastine

Bepotastine is an antihistamine. It is a non-sedating, selective antagonist of the histamine 1 receptor. It was approved in Japan for use in the treatment of allergic rhinitis, uriticaria and puritus.

Properties Suppliers
Beta Glucan

Beta Glucans are polysaccharides of D-glucose monomers linked by β-glycosidic bonds.β-Glucans are a diverse group of molecules that can vary with respect to molecular mass, solubility, viscosity, and three-dimensional configuration.Beta glucan is a unique polysaccharide composed of glucose molecules extracted and purified from the cell wall of common baker's yeast Saccharomyces cerevisiae. It is used to maintain or stimulate the effectiveness of the immune system.β-Glucans occur most commonly as cellulose in plants, the bran of cereal grains, the cell wall of baker's yeast, certain fungi, mushrooms and bacteria.It is ideally suited to reduce fat in mayonnaise, dressings and dips as opposed to traditional starches.

Properties Suppliers
Bethanechol

Bethanechol is a parasympathomimetic (cholinergic) used for the treatment of acute postoperative and postpartum nonobstructive (functional) urinary retention and for neurogenic atony of the urinary bladder with retention. Bethanechol, a cholinergic agent, is a synthetic ester which is structurally and pharmacologically related to acetylcholine. It increases the tone of the detrusor urinae muscle, usually producing a contraction sufficiently strong to initiate micturition and empty the bladder. It stimulates gastric motility, increases gastric tone, and often restores impaired rhythmic peristalsis. Bethanechol chloride is not destroyed by cholinesterase and its effects are more prolonged than those of acetytcholine. Bethanechol directly stimulates cholinergic receptors in the parasympathetic nervous system while stimulating the ganglia to a lesser extent. Its effects are predominantly muscarinic, inducing little effect on nicotinic receptors and negligible effects on the cardiovascular system.

Properties
Bevacizumab

Bevacizumab is an angiogenesis inhibitor, a drug that slows the growth of new blood vessels.Bevacizumab is a humanized monoclonal antibody that inhibits vascular endothelial growth factor A (VEGF-A).Bevacizumab has recently been used by ophthalmologists in an off-label use as an intravitreal agent in the treatment of proliferative (neovascular) eye diseases, particularly for choroidal neovascular membrane (CNV) in AMD.

Properties Suppliers
Bezafibrate

Bezafibrate is a fibrate drug used for the treatment of hyperlipidaemia. It helps to lower low density lipoproteins cholesterol and triglyceride in the blood, and increase high density lipoproteins.

Properties Suppliers
Bicuculline

Bicuculline is a light-sensitive competitive antagonist of GABAA receptors. It was originally identified in 1932 in plant alkaloid extracts and has been isolated from Dicentra cucullaria, Adlumia fungosa, Fumariaceae, and several Corydalis species.Bicuculline is also a pharmcological agent that, when used, increases the frequency of occurrence of ocular saccades during visual fixation.

Properties Suppliers
Bremazocine

Bremazocine is a κ-opioid receptor agonist related to pentazocine. It has potency and long-lasting analgesic and diuretic effects.

Properties
Brofaromine

Brofaromine is a reversible inhibitor of monoamine oxidase A primarily useful in the treatment of depression and anxiety. It also has serotonin reuptake inhibitory properties and its dual pharmacologic effects offer promise in the treatment of a wide spectrum of depressed patients while producing less severe anticholinergic side effects in comparison with standard drugs although it is not commercially available and is not being actively researched, possibly due to a lack of financial interest.

Properties
Bupivacaine

Bupivacaine is a local anaesthetic drug belonging to the amino amide group. Bupivacaine is indicated for local anesthesia including infiltration, nerve block, epidural, and intrathecal anesthesia. Bupivacaine often is administered by epidural injection before total hip arthroplasty. It also is commonly injected to surgical wound sites to reduce pain for up to 20 hours after the surgery. Bupivacaine binds to the intracellular portion of sodium channels and blocks sodium influx into nerve cells, which prevents depolarization.
