Pachybasin is an anthraquinone fungal metabolite. Pachybasin shows antimicrobial activities against E. coli, B. subtilis, M. luteus, S. cerevisiae, C. albicans, A. niger, and A. flavus, with MIC values of 64.0 μg/mL, and against S. aureus and F. oxysporum with MIC values of 32.0 and 16.0 μg/mL respectively.

Aureusimine B, also known as phevalin, is a natural pyrazinone produced by certain fungi and by Staphylococcus spp., including S. aureus. Its synthesis appears to be initiated by a conserved nonribosomal peptide synthetase that creates a dipeptide (phenylalanine-valine) aldehyde, which then undergoes cyclization and oxidation. Aureusimine B inhibits calpain in a casein hydrolysis assay (IC50 = 1.3 μM), contributes to S. aureus infection in mice, and alters human keratinocyte gene expression.

HYPOCRELLIN B are photosensitive pigments isolated from Hypocrella bambusae Sacc. Hypocrellin B causes DNA strand breakage, induces apoptosis in ovarian cancer cells, and inhibits proliferation of Staphylococcus by increasing ROS levels, and damaging cell

Mycaminosyltylonolide is a macrolide antibiotic that is tylonolide having a beta-D-mycaminosyl residue attached at position 5. Mycaminosyltylonolide is a potent antibiotic with antibacterial activity and inhibits luciferase synthesis.

(-)-Corynoxidine is an AChE inhibitor derived from tubers of Stephania succifera. Corynoxidine exhibits antibacterial activities against Staphylococcus aureus and methicillin-resistant Staphylococcus aureus strains in different degrees.

Isovalerylshikonin is a natural product from Arnebia euchroma

Kaempferol-7,4'-dimethyl ether, isolated from the rhizomes of Zingiber phillipseae, exhibits antioxidant activity against S. aureus and E. coli with MICs of 200 and 225 μg/ml, respectively.

Sanguisorbigenin (Tomentosolic acid) is a natural antimicrobial agent that inhibits methicillin-resistant Staphylococcus aureus (MRSA).

Coreoside B is isolated from coreoside and showed weak antimicrobial activity against S. aureus and B. anthracis.

Blasticidin S HCl is a natural product and an inhibitor of protein synthesis. Blasticidin S HCl is a broad-spectrum antibiotic that can inhibit the cell growth of prokaryotes, fungi, plants and mammalian cells.

Moracin C, a natural compound found in Morus mesozygia, Morus alba var. multicaulis, is an anti-inflammatory agent. moracin C inhibits nitric oxide (NO) release and LPS-activated reactive oxygen species (ROS) in cells.

Lauric Acid (Dodecylic acid),which is found naturally in various plant and animal fats and oils, is a saturated medium-chain fatty acid with a 12-carbon backbone. It is a major component of coconut oil and palm kernel oil.

Dihydropinosylvinin is an phytoalexin, it shows antifungal activity against Cladosporium cladosporioides, Botryodiplodia theobromae, Aspergillus niger and Penicillium schlerotgenum, it also exhibits strong antibacterial activity against Bacillus cereus, S

Viridicatol, with potent antibacterial activity against Staphylococcus aureus(MIC: 15.6 μg/mL), is isolated from the fermentation of an endophytic fungus Penicillium sp. R22 in Nerium indicum.

Mahanimbine is found in the roots, leaves and stems of Murraya koenigii and is an orally active alkaloid extracted from Murraya koenigii. Bifidobacterium bifidum leaves on histopathological changes in pancreatic beta cells of streptozotocin-induced diabetic rats.

m-Tolylacetic acid is a phenylacetic acid derivative exhibiting antibacterial activity against S. aureus.

Citromycetin is a fungal metabolite originally isolated from Australian P. frequentans. It has antibiotic activity against the Gram-negative bacteria V. cholerae and S. flexneri and the Gram-positive bacteria S. aureus.

Violacein is a bacterial metabolite originally isolated from C. violaceum that has antibacterial and antiprotozoal activities.[1] [2] It is produced by C. violaceum as a purple pigment in response to N-hexanoyl homoserine lactone , a property that has been modified to create a strain of C. violaceum used in detecting quorum-sensing molecules.[3] Violacein is active against Gram-positive bacteria, including B. subtilis and S. aureus (MICs = 0.8 and 1.6 µM, respectively). It is also active against P. falciparum, including chloroquine-susceptible and -resistant strains (IC50s = 0.85 and 0.63 µM, respectively).[2] It reduces parasitemia in a mouse model of nonlethal P. chabaudi chabaudi infection when administered at a dose of 7.5 mg/kg and increases survival in a mouse model of lethal P. chabaudi chabaudi infection. Violacein permeabilizes the cytoplasmic membrane of bacterial cells but does not affect the cell wall.[1]
