1. Deoxyshikonin (Arnebin 7) may be a new drug candidate for wound healing and treatment of lymphatic diseases. 2. Deoxyshikonin enhances the ability of human dermal lymphatic microvascular endothelial cells (HMVEC-dLy) to undergo time-dependent in vitro cord formation. 3. Deoxyshikonin and dodecyl gallate show significantly synergic antimicrobial activity with penicillin in vivo and in vitro, and can effectively reduce nasopharyngeal and lung colonization caused by different penicillin-resistant pneumococcal serotypes.
Menadione (Vitamin K3) is a synthetic naphthoquinone without the isoprenoid side chain and biological activity, but can be converted to active vitamin K2, menaquinone, after alkylation in vivo.
Deoxylapachol has anti-wood rot activity, it can inhibit the brown rot fungi Gloeophyllum sepiarium CBS 353.74 and Gloeophyllum trabeum CBS 318.50 and the white rot fungi Merulius tremellosus CBS 280.73 and Phlebia brevispora CBS 509.92. It also can induc
Tanshinone IIA (Tanshinone B) is a diterpene quinone natural product that targets the protein kinase domain of VEGF/VEGFR2. Tanshinone IIA inhibits angiogenesis and exhibits anti-inflammatory, antioxidant, and therapeutic activities against coronary heart disease.
Cryptotanshinone (Cryptotanshinon), a STAT3 inhibitor (IC50: 4.6 μM) in a cell-free assay, strongly inhibits phosphorylation of STAT3 Tyr705, with a little effect on STAT3 Ser727, but no inhibition for STAT1 nor STAT5.
Juglone (Regianin) is a natural naphthoquinone found in the black walnut (J. nigra) and other plants in the Juglandaceae family. Juglone also irreversibly inhibits peptidyl-prolyl cis/trans isomerases of the parvulin family, including human Pin1, yeast Ess1/Ptf1, and E. coli parvulin (Ki = 55.9 nM). Juglone also blocks transcription by RNA polymerases I, II, and III (IC50s = 2-7 μM) and attenuates kidney fibrosis in rats treated with unilateral ureteral obstruction, both through Pin1-independent mechanisms.
Lawsone methyl ether (2-Methoxy-1,4-naphthoquinone) induces apoptosis in A549 cells independently of cell cycle arrest, mediated by JNK and p38 MAPK signaling pathways. These pathways are activated due to oxidative DNA damage from increased ROS generation in MNQ-treated A549 cells.
Lawsone (Hennotannic acid) (2-hydroxy-1,4-naphthoquinone), also known as hennotannic acid, is a red-orange dye present in the leaves of the henna plant (Lawsonia inermis) as well as in the flower of water hyacinth (Eichhornia crassipes).
Lapachol (CI75490) has antimicrobial properties against many pathogens. It has anti-inflammatory, analgesic and antibiotic properties. It is an inhibitor of epithelial tumors in Drosophila melanogaster heterozygote.
Danshenxinkun A is a natural product isolated from Salvia miltiorrhiza (Tanshen) exhibiting neuraminidase inhibitory activity with an IC50 of 39.5 mg/L.
Tanshinol B, a bioactive component isolated from the 50% ethanol extract of Salvia miltiorrhiza roots and rhizomes, is also found in Seaweed prowazekii [1].
Tiancimycin A (TNM A) is an anticancer compound that induces rapid DNA damage, cell cycle arrest, and apoptosis. It can be isolated from the Streptomyces genus, specifically strain CB03234.
Hibarimicin B (Angelmicin B) is a tyrosine kinase inhibitor that selectively inhibits the activity of src tyrosine kinase. It does not affect protein kinase A or C. Additionally, it exhibits moderate antibacterial activity against gram-positive bacteria, with a MIC range of 0.8-12.56 μg/mL.
