A novelsesterterpene, cyclolinteinone (4), based on an unprecedented rearranged monocarbocyclic skeleton, has been isolated from Cacospongia cf. linteiformis. and its structure, complete with absolute stereochemistry, determined by spectral studies and chemical correlations. A plausible pathway for the biogenesis of this compound starting from geranylfarnesol is proposed. Cyclolinteinone has been
The present invention is directed to systems and methods for contributing to the local treatment of pain. More specifically, the present invention is directed to the use of one or more NFKB inhibiting compounds, particularly clonidine, in the manufacture of a medicament for the treatment of pain wherein said medicament is for local administration to a patient in need thereof.

The invention involves the treatment, prevention, and reduction of immunoinflammatory disorders involving the combination of an agent that increases the signal activity of a glucocorticoid receptor (e.g., glucocorticoid receptor agonist) and an agent that modulates the signaling activity of one or more signaling pathways selected from the NF-κB pathway, NFAT pathway, AP-1 pathway, and Elk-1 pathway such that proinflammatory cytokine secretion or production, or any other inflammatory response, is reduced. Further, screening methods are provided for identifying candidate compounds and strategies useful for treating, preventing, or reducing such conditions.
This invention pertains to the identification of two novel epithelial signaling pathways in ER-positive breast cancer s and the discovery that the cellular biology and (likely also the clinical outcome) of ER-positive breast cancer cells is unexpectedly altered when these signaling pathways are activated. The first pathway pertains to the discovery that NF-κB activation and/or DNA binding is implicated in the etiology of ER-positive breast (and other) cancers. The second pathway involves ligand-independent quinine-mediated ER activation by posphorylation (e.g. on SER-118 and SER-167 residues of ER) and nuclear translocation of full-length (67 kDA) ER as well as the phorphorylating activation of a truncated and nuclear-localized ER variant (˜52 kDa).
本发明涉及在ER阳性乳腺癌中发现两种新型上皮信号通路,并发现当这些信号通路被激活时,ER阳性乳腺癌细胞的细胞生物学特性和(可能还有临床结果)会发生意想不到的改变。第一条途径是发现 NF-κB 激活和/或 DNA 结合与 ER 阳性乳腺癌(和其他癌症)的病因有关。第二种途径涉及与配体无关的奎宁介导的ER激活,即ER的正理论化(如ER的SER-118和SER-167残基)和全长(67 kDA)ER的核转位,以及截短的核定位ER变体(˜52 kDa)的正理论化激活。
