Evans blue
T-1824 or Evans blue, often incorrectly rendered as Evan’s blue, is an azo dye that has a very high affinity for serum albumin. Because of this, it can be useful in physiology in estimating the proportion of body water contained in blood plasma. It fluoresces with excitation peaks at 470 and 540 nm and an emission peak at 680 nm. Evans blue dye has been used as a viability assay on…

Adenosine
Adenosine (symbol A) is an organic compound that occurs widely in nature in the form of diverse derivatives. The molecule consists of an adenine attached to a ribose via a β-N9–glycosidic bond. Adenosine is one of the four nucleoside building blocks of RNA (and its derivative deoxyadenosine is a building block of DNA), which are essential for all life. Its derivatives include the energy carriers adenosine mono-, di-, and triphosphate, also…

Melanin-concentrating hormone (MCH) aka PMCH
Melanin-concentrating hormone (MCH), also known as pro-melanin stimulating hormone (PMCH), is a cyclic 19-amino acid orexigenic hypothalamicpeptide originally isolated from the pituitary gland of teleost fish, where it controls skin pigmentation. Barson JR, Morganstern I, Leibowitz SF (2013). “Complementary roles of orexin and melanin-concentrating hormone in feeding behavior”. International Journal of Endocrinology. 2013: 983964. doi:10.1155/2013/983964. PMC 3727095. PMID 23935621. In mammals it is involved in the regulation of feeding behavior, mood,…

The drug phencyclidine (PCP or ‘Angel Dust’) antagonizes glutamic acid non-competitively at the NMDA receptor
The drug phencyclidine (more commonly known as PCP or ‘Angel Dust’) antagonizes glutamic acid non-competitively at the NMDA receptor. For the same reasons, dextromethorphan and ketamine also have strong dissociative and hallucinogenic effects. Acute infusion of the drug LY354740 (also known as eglumegad, an agonist of the metabotropic glutamate receptors2 and 3) resulted in a marked diminution of yohimbine-induced stress response in bonnet macaques (Macaca radiata); chronic oral administration of LY354740 in those animals led to markedly reduced baseline cortisol levels…

Oxalyldiaminopropionic acid (ODAP) is a structural analogue of the neurotransmitter glutamate found in the grass pea Lathyrus sativus
Oxalyldiaminopropionic acid (ODAP) is a structural analogue of the neurotransmitter glutamate found in the grass pea Lathyrus sativus. It is the neurotoxin responsible for the motor neuron degeneration syndrome lathyrism.
