2-Methylheptanoic acid is a naturally occurring branched-chain medium-chain fatty acid with fumigant activity against Aspergillus flavus. 2-Methylheptanoic acid inhibits the growth of Aspergillus flavus and kills its spores via two modes of action, namely fumigation and direct contact, with its fumigant activity being stronger than its direct contact activity. 2-Methylheptanoic acid can be used in studies related to Aspergillus flavus infection.

Alkaline Phosphatase (Apase), Escherichia coli is an alkaline phosphatase from Escherichia coli, and is one of the most active alkaline phosphatases. Alkaline phosphatase, Escherichia coli is an orally active membrane-bound glycoprotein that catalyzes the hydrolysis of phosphate monoesters at alkaline pH. Alkaline phosphatase, Escherichia coli reduces myeloperoxidase activity and bacterial translocation. Alkaline phosphatase, Escherichia coli improves survival rate of mice infected with E. coli. Alkaline phosphatase, Escherichia coli improves TNBS-induced colon inflammation.

2,4-Dichlorobenzenesulfonyl chloride (Compound 6d) is a heterocyclic building block, which can be used in the synthesis of nicotinyl arylsulfonylhydrazides with anticancer and antibacterial activities.

Hecogenin acetate is an orally active steroid saponin aglycone with extensive biological activities. Hecogenin acetate inhibits the phosphorylation of NF-κB and p38 MAPK signaling pathways, antagonizes TRPA1/TRPM8 channels, inhibits the production of pro-inflammatory cytokines, and has anti-inflammatory and analgesic effects. Hecogenin acetate inhibits the production of ROS and the activation of NLRP3 inflammasome; downregulates the expression of MMP-2, and has neuroprotective and anti-tumor activities. Hecogenin acetate enhances gastric mucosal defense and promotes ulcer healing. Hecogenin acetate can be used in combination with certain antibiotics to regulate bacterial efflux pumps and restore antibiotic sensitivity.

HADA hydrochloride (HCC-Amino-D-alanine hydrochloride) is a blue (λ_em~450 nm) fluorescent D-amino acid (FDAA). FDAAs are efficiently incorporated into the peptidoglycans (PGs) of diverse bacterial species at the sites of PG biosynthesis, allowing specific and covalent probing of bacterial growth with minimal perturbation.
Solvent and concentration: DMSO: 50 mM

5-O-(E)-p-Coumaroylquinic acid, a quinic acid derivative, is a potent phytochemical agent against hepatitis B virus.

Protein serine/threonine kinase (Ser/Thr protein kinase) is a signal transduction molecule. Protein serine/threonine kinase phosphorylates specific residues on target substrates, regulates phosphorylation-dependent signal cascades, modulates cellular processes of mycobacteria, blocks phagosome-lysosome fusion, promotes meiotic maturation of Xenopus laevis (African clawed frog) oocytes, rescues the phenotype of Saccharomyces cerevisiae (budding yeast) CDC5 mutants, and exhibits cell cycle phase-specific kinase activity. Protein serine/threonine kinase maintains a tightly regulated cell cycle expression pattern, and sustains the growth and survival of mycobacteria. Protein serine/threonine kinase can be used in studies related to tuberculosis.

DL-threo-2-methylisocitrate sodium salt is a substrate of isocitrate lyase 1 (ICL1).

4-Phenoxybenzylamine inhibits the function of the NS3 protein by stabilizing an inactive conformation with an IC₅₀ of about 500 μM against FL NS3/4a.

Quercetin pentaacetate could interact with F-protein with lower binding energy and better stability to block viral adhesion. Quercetin pentaacetate interacts with RSV and inhibit the viral adhesion on cell surface.

Celestine Blue is a electroactive indicator in DNA biosensors. Celestine Blue is strongly adsorbed on the spinel phases and CNT (carbon nanotubes), facilitates dispersion, acts as a capping agent and allows for the fabrication of spinel decorated CNT. Celestine Blue is an efficient charge transfer mediator, which allows for significant improvement of capacitive behavior. TiO₂ nanoparticles doped with Celestine Blue can be used as a label in a sandwich immunoassay for the hepatitis C virus (HCV) core antigen.

Stigmasta-4,22-dien-3-one is an antitubercular agent. Stigmasta-4,22-dien-3-one shows cytotoxicity against human HT1080 tumoral cell line with an IC₅₀ of 0.3 mM.

Desmethyl ferroquine (SSR97213) is the active and major metabolite of Ferroquine. Ferroquine is an antimalarial. Desmethyl ferroquine shows significant activity against Chloroquine-susceptible and resistant P. falciparum strains.

5'-O-DMT-2'-TBDMS-Uridine is a deoxyribonucleoside used for the oligonucleotide synthesis.

1E7-03, a low MW tetrahydroquinoline derivative targeting protein phosphatase-1, can inhibit HIV-1 transcription.

N-Butanoyl-DL-homoserine lactone ((Rac)-C4-HSL) is a racemic mixture of N-Butanoyl-D-homoserine lactone and N-Butanoyl-L-homoserine lactone.
