Neocarzinostatin is an effective DNA-damaging, anti-tumor antibiotic. It recognizes double-stranded DNA bulge and induces DNA double strand breaks (DSBs). Neocarzinostatin leads to apoptosis. Neocarzinostatin has potential for EpCAM-positive cancer treatment.
Osteocalcin (1-49) is a non-collagenous peptide that is secreted by osteoblasts and odontoblasts and comprises 1-2% of the total protein in bone. Secretion of osteocalcin (1-49) is stimulated by 1,25-dihydroxy vitamin D and plasma levels increase in diseases that induce dysregulated bone turnover such as osteoporosis, Paget's disease, and primary hyperparathyroidism. Osteocalcin (1-49) is positively correlated with insulin sensitivity and negatively correlated with high blood glucose levels in women. In vitro, osteocalcin induces chemotaxis of MDA-MB-231 breast cancer cells, human peripheral blood monocytes, and rat osteosarcoma cells with osteoblast-like characteristics. It is also expressed by vascular smooth muscle cells (VSMCs) displaying an osteoblast-like phenotype and has been positively associated with calcification of aortic tissue and heart valves in humans.
cis-9,10-Methyleneoctadecanoic acid is a cyclopropane fatty acid that has been found in bacteria and the digestive gland of P. globosa. It is a component of S. aureus cell membranes and levels decrease upon treatment with carvacrol. cis-9,10-Methyleneoctadecanoic acid is secreted by H. pylori and enhances histamine- and dibutyryl cAMP-stimulated acid secretion in isolated guinea pig parietal cells. It also activates protein kinase C (PKC) in a calcium-dependent manner.
Cis-9,10-Methyleneoctadecanoic acid methyl ester, a cyclopropane fatty acid methyl ester, stimulates DNA synthesis in rat hepatocytes and serves as a standard for quantifying cis-9,10-methyleneoctadecanoic acid in bacterial membranes through co-chromatography. [Matreya, LLC. Catalog No. 1823]
Neochamaejasmin A can inhibit cellular (3)H-thymidine incorporation (IC 50 12.5 microg mL) and subsequent proliferation of human prostate cancer LNCaP cells, it blocks cell cycle progression at the G1 phase by activating the p21 protein and ultimately pro
