Sulfonylureas (UK: sulphonylurea) are a class of organic compounds used in agriculture.
Sulfonylureas used as herbicides.
A large number of sulfonylureas are used as herbicides. They function by interfering with biosynthesis of the amino acids valine, isoleucine, and leucine. Compounds in this class include amidosulfuron, azimsulfuron, bensulfuron-methyl, chlorimuron-ethyl, chlorsulfuron, ethametsulfuron-methyl, cinosulfuron, ethoxysulfuron, flazasulfuron, flupyrsulfuron-methyl-sodium, imazosulfuron, metsulfuron-methyl, nicosulfuron, oxasulfuron, primisulfuron-methyl, prosulfuron, pyrazosulfuron-ethyl, rimsulfuron, sulfometuron-methyl, sulfosulfuron, thifensulfuron-methyl, triasulfuron, tribenuron-methyl, and triflusulfuron-methyl.
Piracetam is a Nootropic that displays cognitive enhancing properties. Piracetam is a modulator of neurotransmitter-induced ion flux and is proposed to enhance neurotransmission via this modulation. Through AMPA receptors, Piracetam potentiates Na+ influx. Piracetam also facilitates the efficiency of cholinergic neurotransmission at muscarinic receptors.

Amyl nitrite is a rapidly acting vasodilator administered by inhalation. 0.3 ml is supplied in a covered thin glass capsule which is easily crushed between the fingers. Amyl nitrite is a clear, yellowish liquid having a peculiar ethereal, fruity odor. It is volatile, even at low temperatures, and is flammable. This product is stabilized with Flexol(tm) 2 percent. The structural formula of amyl nitrite is: C5H11NO2.
Amyl nitrite causes a non specific relaxation of smooth muscle with the most prominent actions occurring in vascular smooth muscle. This effect on vascular smooth muscle results in coronary vasodilation and decreased systemic vascular resistance and left ventricular preload and afterload. Myocardial ischemia is relieved in patients with angina pectoris, with an abatement of chest pain and possibly other related symptons. Amyl nitrite vapors are absorbed rapidly through the pulmonary alveoli, manifesting therapeutic effects within one minute after inhalation. The drug is metabolized rapidly, probably by hydrolytic denitration; approximately one-third of the inhaled amyl nitrite is excreted in the urine.
Amyl nitrite is indicated for the rapid relief of angina pectoris. Its effect appears within 30 seconds and lasts for approximately 3 to 5 minutes.
Since it may increase intraocular and intracranial pressures, amyl nitrite is contraindicated or should be used with great caution in patients with glauc
oma, recent head trauma or cerebral hemorrhage. Amyl nitrite can cause harm to the fetus when it is administered to a pregnant woman because it significantly reduces systemic blood pressure and blood flow on the maternal side of the placenta.
Application: For the treatment of backache and ankylosing spondylitis.
