Cytoglobosin D, a cytochalasan derivative, displays cytotoxic activity toward the A-549 cell line (IC50=2.55 μM).

Cytoglobosin C, a cytochalasan derivative, shows potent cytotoxicity against both SGC-7901 and A549 cell lines (IC50<10 μM).

Burnettramic acid A aglycone is a fungal metabolite found in Aspergillus burnettii.

Trichodecenin I, a fungal metabolite, is a peptaibol composed of 7 amino acid residues.

β-Alanine-15N (2-Carboxyethylamine-15N) is the 15N-labeled β-Alanine. β-Alanine is a non-essential amino acid that is shown to be metabolized into carnosine, which functions as an intracellular buffer.

Sarcosine-15N (N-Methylglycine-15N) is the 15N-labeled Sarcosine. Sarcosine (N-Methylglycine), an endogenous amino acid, is a competitive glycine transporter type I (GlyT1) inhibitor and N-methyl-D-aspartate (NMDA) receptor co-agonist. Sarcosine increases the glycine concentration, resulting in an indirect potentiation of the NMDA receptor. Sarcosine is commonly used for the research of schizophrenia.

L-Serine-15N ((-)-Serine-15N) is the 15N-labeled L-Serine. L-Serine ((-)-Serine; (S)-Serine), one of the so-called non-essential amino acids, plays a central role in cellular proliferation.

D-Glucose-13C2-4 is the 13C labeled D-Glucose. D-Glucose (Glucose), a monosaccharide, is an important carbohydrate in biology. D-Glucose is a carbohydrate sweetener and critical components of the general metabolism, and serve as critical signaling molecules in relation to both cellular metabolic status and biotic and abiotic stress response.

D-Glucose-13C2 (Glucose-13C2) is the 13C labeled D-Glucose. D-Glucose (Glucose), a monosaccharide, is an important carbohydrate in biology. D-Glucose is a carbohydrate sweetener and critical components of the general metabolism, and serve as critical signaling molecules in relation to both cellular metabolic status and biotic and abiotic stress response.

Octanoic acid-13C4 (Caprylic acid-13C4) is the 13C labeled Octanoic acid. Octanoic acid (Caprylic acid) is an oily liquid with a slightly unpleasant rancid taste and used commercially in the production of esters used in perfumery and also in the manufacture of dyes.

Isovaleric acid-13C is the 13C labeled Isovaleric acid. Isovaleric acid is a natural fatty acid and known to effect on neonatal death and possible Jamaican vomiting sickness in human.

L-Methionine-13C is the 13C-labeled L-Methionine. L-Methionine is the L-isomer of Methionine, an essential amino acid for human development. Methionine acts as a hepatoprotectant.

L-Methionine-1-13C is the 13C-labeled L-Methionine. L-Methionine is the L-isomer of Methionine, an essential amino acid for human development. Methionine acts as a hepatoprotectant.

L-Proline-13C is the 13C-labeled L-Proline. L-Proline is one of the twenty amino acids used in living organisms as the building blocks of proteins.

L-Glutamic acid-5-13C is the 13C-labeled L-Glutamic acid. L-Glutamic acid acts as an excitatory transmitter and an agonist at all subtypes of glutamate receptors (metabotropic, kainate, NMDA, and AMPA). L-Glutamic acid shows a direct activating effect on the release of DA from dopaminergic terminals.
