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
