3-Hydroxybenzaldehyde is a compound useful in organic synthesis.

DL-Isocitric acid trisodium salt is the protonated form of isocitrate, a substrate in the citric acid cycle. It is useful as a marker for determining the composition of isocitrates in fruit products, including fruit juices.

Arazine (N-Acetyl-S-farnesyl-L-cysteine) is a cell-permeable modulator of G protein and GPCR signaling, and it can act as a substrate for isoprenylcysteine methyltransferase by competing with prenylated G protein or its receptor sites.

Galanthamine N-Oxide, an alkaloid extracted from Zephyranthes concolor bulbs, effectively inhibits acetylcholinesterase (AChE) from electric eel with an EC50 of 26.2 μM. It acts as a significant inhibitor of substrate accommodation within the active sites of Torpedo californica AChE (TcAChE), human AChE (hAChE), and human BChE (hBChE) enzymes.

Nadolol is a non-selective beta-adrenergic antagonist with antihypertensive and antiarrhythmic activities. Nadolol competitively blocks beta-1 adrenergic receptors located in the heart and vascular smooth muscle, inhibiting the activities of the catechola

4-Nitrophenyl α-D-galactopyranoside (PNP-alpha-D-Gal) is an artificial substrate of 4-nitrophenyl (pNP) glycopyranoside used for detecting α-galactosidase activity. The amount of released pNP increases significantly when PNP-alpha-D-Gal is used as a substrate.

Hydroxypyruvic acid lithium hydrate is an intermediate in the metabolism of serine, glycine, and threonine. It is a substrate for serine-pyruvate aminotransferase and glyoxylate reductase/hydroxypyruvate reductase.

Mephenytoin (Phenantoin) is an anticonvulsant and a substrate of CYP2C19 and CYP2B6.

H-D-Phe-Pip-Arg-pNA dihydrochloride (S-2238 dihydrochloride), a chromogenic substrate, mimics the N-terminal fragment of the A alpha chain of fibrinogen, the native substrate of thrombin. Specifically designed for thrombin detection, it is employed for quantifying antithrombin-heparin cofactor (AT-III) and is characterized by its sensitivity, accuracy, and ease of implementation.

Necrosulfonamide ((E)-Necrosulfonamide) is a necroptosis inhibitor that targets MLKL and is selective. Necrosulfonamide prevents the MLKL-RIP1-RIP3 necrosomal complex from interacting with its downstream effectors.

trans-4-Hydroxycyclohexanecarboxylic Acid is an organic intermediate.

Convallatoxin is a natural product

(-)-Isocorypalmine ((S)-Tetrahydrocolumbamine), a natural product isolated from Corydalis chaerophylla, has significant antifungal activity.

MBP MAPK Substrate acetate can be used as an exogenous substrate for MAPK.

Sakamototide substrate peptide acetate is a peptide substrate of AMPK kinase family and can be used for the determination of kinase activity.

Calcineurin substrate acetate is from the regulatory RII subunit of cAMP-dependent protein kinase.

PKG Substrate acetate is a selective substrate for cGMP-dependent protein kinase (PKG).PKG Substrate is a selective substrate for protein kinase G (PKG) with a strong preference for PKG Iα (Km = 59 μM) over PKG II (Km = 305 μM).

HSV-TK substrate is an antitumor agent that induces multi-log cytotoxicity in both HSV-TK-expressing and bystander cells.

Cyclin-dependent kinase 5 (Cdk5) is a serine/threonine kinase that is predominantly active in neuronal tissues. With p25 or p35, Cdk5 phosphorylates a range of proteins, including histone H1 and tau. Cdk5 substrate is a synthetic peptide (PKTPKKAKKL) corresponding to a sequence of histone H1. It is phosphorylated by Cdk5 with a Km value of 5 μM.

Cdk5 Substrate acetate is a synthetic peptide (PKTPKKAKKL) corresponding to a sequence of histone H1. It is phosphorylated by Cdk5 with a Km value of 5 µM.

Cathepsin D and E FRET Substrate acetate is a fluorogenic substrate for cathepsins D and E but not for B, H, or L. Cathepsin D and E FRET Substrate acetate can be used in mechanistic studies on cathepsins D and E studies.

Cathepsin D and E FRET Substrate acetate is a fluorogenic substrate selectively cleaved by cathepsins D and E at the Phe-Phe amide bond, demonstrating no activity towards cathepsins B, H, or L. This specificity renders it essential for routine assays and mechanistic studies focusing on cathepsins E and D[1].
