2-Phenylglycine (DL-α-Phenylglycine) is a metabolite present in breast milk during lactation.

KL 001 is a Cryptochrome protein (CRY) stabilizer. KL001 prevented ubiquitin-dependent degradation of CRY, resulting in lengthening of the circadian period. KL001-mediated CRY stabilization inhibited glucagon-induced gluconeogenesis in primary hepatocytes. KL001 thus provides a tool to study the regulation of CRY-dependent physiology and aid development of clock-based therapeutics of diabetes.

Levofloxacin hydrate (Cravit hydrate) is a broad-spectrum, third-generation fluoroquinolone antibiotic and optically active L-isomer of ofloxacin with antibacterial activity. Levofloxacin diffuses through the bacterial cell wall and acts by inhibiting DNA gyrase (bacterial topoisomerase II), an enzyme required for DNA replication, RNA transcription, and repair of bacterial DNA. Inhibition of DNA gyrase activity leads to blockage of bacterial cell growth.

Levofloxacin ((-)-Ofloxacin) is a synthetic fluoroquinolone antibiotic that inhibits the superhelical activity of bacterial DNA rotamase and prevents DNA replication. Levofloxacin is a broad-spectrum antibiotic used for the treatment of a wide range of bacterial infections.

ML324(IC50=920 nM) is a specific inhibitor of jumonji histone demethylase (JMJD2).

Methacycline hydrochloride (Rondomycin) is a broad-spectrum semisynthetic antibiotic related to TETRACYCLINE but excreted more slowly and maintaining effective blood levels for a more extended period.

Propafenone (Propafenonum) is only found in individuals that have used or taken this drug. It is an antiarrhythmia agent that is particularly effective in ventricular arrhythmias. It also has weak beta-blocking activity. The drug is generally well tolerated. The electrophysiological effect of propafenone manifests itself in a reduction of upstroke velocity (Phase 0) of the monophasic action potential. In Purkinje fibers, and to a lesser extent myocardial fibers, propafenone reduces the fast inward current carried by sodium ions, which is responsible for the drugs antiarrhythmic actions. Diastolic excitability threshold is increased and effective refractory period prolonged. Propafenone reduces spontaneous automaticity and depresses triggered activity. At very high concentrations in vitro, propafenone can inhibit the slow inward current carried by calcium but this calcium antagonist effect probably does not contribute to antiarrhythmic efficacy.

Pyrithioxin (Encefabol) is a neurodynamic compound, combined with a short period of hyperventilation (HV) was applied in cerebral infarct patients with Hemiplegia. Pyrithioxin is regarded as an encephalotropic or nootropic compound and is reported to act mainly by producing decisive improvements in cerebral metabolism.

(R)-(-)-1,3-Butanediol is a novel ketogenic ester that rapidly elevates circulating r- and s-ß-hydroxybutyric acid levels in healthy adults, making it useful for studying metabolic system-related diseases.

Phosphorylethanolamine (O-Phosphorylethanolamine) is a phosphomonoester metabolite of the phospholipid metabolism. Phosphorylethanolamine is a precursor of phospholipid synthesis and a product of phospholipid breakdown. Phosphomonoesters are present at much higher levels in the brain than in other organs. In developing the brain, phosphomonoesters are normally elevated during the period of neuritic proliferation. This also coincides with the occurrence of normal programmed cell death and synaptic pruning in developing the brain. These findings are consistent with the role of phosphomonoesters in membrane biosynthesis. Phosphorylethanolamine shows a strong structural similarity to the inhibitory neurotransmitter, GABA, and the GABAB receptor partial agonist, 3-amino-propylphosphonic acid. Phosphorylethanolamine is a phosphomonoester which is decreased in post-mortem Alzheimer's disease (AD) brain.

Butanoic acid is an endogenous human metabolite, an endogenous histone deacetylase (HDAC) inhibitor. The IC50 of HDAC3, HDAC4 and HDAC1 were 2.4 mM, 4.5 mM and 5.3 mM, respectively. 3-Hydroxybutyric acid has the effects of energy metabolism, neuroprotection, anti-inflammatory, and improvement of insulin resistance.

Dofetilide (UK 68789) is a sulfonamide class III antiarrhythmic agent and potassium channel blocker. Dofetilide selectively blocks cardiac ion channels of the rapid component of the delayed rectifier potassium current Ikr. This antiarrhythmic agent prolongs cardiac action potential duration and effective refractory period due to delayed repolarization without affecting conduction velocity. This results in a normal sinus rhythm. Dofetilide is used in the treatment of atrial fibrillation and flutter.

(E/Z)-GO289, which strongly lengthened circadian period, is a potent and selective inhibitor of CK2. (E/Z)-GO289 exhibited cell type-dependent inhibition of cancer cell growth that correlated with cellular clock function. The discovery of (E/Z)-GO289 provides a direct link between the circadian clock and cancer regulation and reveals unique design principles underlying kinase selectivity.
