a. alternata

"Methyl 4-hydroxycinnamate is an esterified derivative of p-coumaric acid isolated from the flowers of Trixis michuacana var. longifolia, exhibiting antibacterial and anti-melanogenesis properties."

Maculosin is a secondary metabolite of fungi and bacteria.

Fungi extract, alternaria alternata, is an allergen obtained from samples of the Alternaria alternata species. It is utilized as an allergen in allergy research.

Tirzepatide sodium is the sodium salt form of a dual glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonist peptide drug that enhances insulin secretion and improves glycemic control by simultaneously activating GIP and GLP-1 receptors. In research and clinical settings, Tirzepatide sodium has also demonstrated effects in reducing body weight and improving metabolic parameters, and is used in studies related to type 2 diabetes and metabolic disorders.

Oligomycin C is a macrolide antibiotic produced by actinomycetes of the genus Streptomyces and belongs to the oligomycin family. It exhibits significant inhibitory activity against various plant pathogenic fungi, including Aspergillus niger, Alternaria alternata, Botrytis cinerea, and Phytophthora capsici, while showing essentially no antimicrobial activity against bacteria, thereby demonstrating selective antifungal properties.

Altertoxin I (Dihydroalterperylenol) is a quinone-type mycotoxin produced by the fungi Alternaria alternata. It exhibits mutagenic and cytotoxic properties and can mildly disrupt metabolic communication.

Antifungalagent 125 (compound 4H) is a potent succinate dehydrogenase (SDH) inhibitor with an IC50 of 3.59 μg/mL and exhibits fungicidal activity against Alternaria alternata.

4'-Demethylpodophyllotoxone, an intermediate in the biotransformation pathway of Alternaria alternata S-f6, undergoes further modification with 4-(2,3,5,6-tetramethylpyrazine-1) (4-TMP). This modification yields a novel compound that exhibits potent inhibitory effects on the human gastric cancer cell line BGC-823 [1].

(3ξ,4ξ,5ξ,6ξ,7ξ,11ξ)-3,6-Dihydroxy-8-oxo-9-eremophilene-12-oic acid, a phytotoxin recently identified in Alternaria alternata ssp. tenuissima isolates, is linked to fruit spots on apples.

Neoaspergillic acid (NSC 356436) (Compound 2) is a secondary metabolite produced by microorganisms. It is isolated from the endophytic fungus Aspergillus sp. SPH2 and exhibits potent antifungal activity against Alternaria alternata, Botrytis cinerea, and Fusarium oxysporum. This compound appears during the exponential growth phase of fungi and also shows antitumor and antibacterial properties.

A mixture of (E)-octadecyl p-coumarate and (Z)-octadecyl p-coumarate has antifungal activity , it shows the dose dependent inhibition of the spore germination of Alternaria alternata and A. porri.

Altertoxin III is a mutagenic agent that induces mutations in Salmonella typhimurium strains TA98, TA100, and TA1537. It is isolated from extracts of A. alternata strains that demonstrate mutagenic responses in the Ames Salmonella typhimurium test.
