L-Cysteic acid monohydrate (3-Sulfo-L-alanine Monohydrate) is an oxidation product of L-cysteine that may be used as a competitive inhibitor of the bacterial aspartate: alanine antiporter (AspT) exchange of aspartate and in other aspartate biological systems. L-Cysteic acid monohydrate is used in monomeric surfactant development. L-Cysteic acid monohydrate may be used in studies of excitatory amino acids in the brain, such as those that bind to cysteine sulfinic acid receptors. It is a useful agonist at several rat metabotropic glutamate receptors (mGluRs).

Neurotensin TFA (39379-15-2 free base) is an endogenous 13 amino acid neuropeptide with profound opioid-independent analgesic effects. It behaves as a neurotransmitter in the brain, as a hormone in the gut, and also as a neuromodulator. It is implicated in the pathophysiology of several CNS disorders (including schizophrenia, Parkinson's disease, drug abuse, pain, cancer, inflammation, eating disorders, and central control of blood pressure) due to its association with a wide variety of neurotransmitter systems such as dopaminergic, sertonergic, glutamatergic, GABAergic, and cholinergic systems. It has a role as a human metabolite, a mitogen, a neurotransmitter and a vulnerary.

NPT200-11 is an orally bioavailable and brain penetrating inhibitor of accumulation of alpha-synuclein (ASYN) misfolding and aggregation. NPT200-11 can be used in studies about the underlying pathology of synucleinopathies including Parkinson's disease (PD), dementia with Lewy bodies (DLB) and Multiple Systems Atrophy (MSA).

JTP-4819 is a potent and selective prolyl endopeptidase (PEP) inhibitor with potential for treating Alzheimer's disease. At nanomolar concentrations, it inhibited the degradation of substance P, arginine-vasopressin, and thyrotropin-releasing hormone by PEP in supernatants of the rat cerebral cortex and hippocampus. Repeated administration of JTP-4819 reversed the aging-induced decrease in brain substance P-like and thyrotropin-releasing hormone-like immunoreactivity, suggesting it may improve the imbalance of peptidergic neuronal systems that develops with senescence by inhibiting PEP activity. Additionally, JTP-4819 increased acetylcholine release from the frontal cortex and hippocampus, regions closely associated with memory, in both young and aged rats.

CART(62-76)(human,rat) TFA, a neuropeptide encompassing residues 62-76 of the CART peptide, exhibits neurotransmitter-like properties and modulates the striatal noradrenergic system, as well as the corticostriatal and hypothalamic serotoninergic (5-HT) systems in the rat brain [1].

Dynorphin B-29 (Leumorphin) (pig) is a peptide that exhibits multifaceted receptor interactions within the brain and isolated tissue systems. This compound is utilized in the study of immunoreactions [1].

Temozolomide-D3 is the deuterated form of Temozolomide. Temozolomide (T1178) (NSC 362856) is an orally active DNA alkylating agent capable of crossing the blood-brain barrier. It also acts as an autophagy inducer and an apoptosis agent. This compound is effective against tumor cells characterized by low levels of O6-alkylguanine-DNA alkyltransferase (OGAT) and dysfunctional mismatch repair systems. Temozolomide (T1178) exhibits anti-tumor and anti-angiogenic effects.

Prolylleucine (((Benzyloxy)carbonyl)-L-prolyl-D-leucine) is a dipeptide containing branched-chain amino acids.

Neuropeptide Y (22-36), a 15-amino-acid peptide, is a fragment of Neuropeptide Y (NPY), a 36-amino-acid neuropeptide involved in various physiological and homeostatic processes in the central and peripheral nervous systems. NPY, the most abundant peptide in the mammalian central nervous system, is secreted alongside neurotransmitters such as GABA and glutamate.
