cyclin d1 Cyclin D1: Protein encoded by the bcl-1 gene which plays a critical role in regulating the cell cycle. Overexpression of cyclin D1 is the result of bcl-1 rearrangement, a t(11;14) translocation, and is implicated in various neoplasms. | 2.17 | 1 | 0 | | |
sr9243 SR9243: an LXR inverse agonist; structure in first source. SR9243 : A sulfonamide resulting from the formal condensation of the sulfonic acid group of mesitylene-2-sulphonic acid with the amino group of 2-(m-bromophenyl)ethylamine in which the nitrogen is substituted by a 4-[m-(methylsulfonyl)phenyl]benzyl group. | 2.17 | 1 | 0 | bromobenzenes; sulfonamide; sulfone | antineoplastic agent; apoptosis inducer; liver X receptor inverse agonist |
lactoferrin Lactoferrin: An iron-binding protein that was originally characterized as a milk protein. It is widely distributed in secretory fluids and is found in the neutrophilic granules of LEUKOCYTES. The N-terminal part of lactoferrin possesses a serine protease which functions to inactivate the TYPE III SECRETION SYSTEM used by bacteria to export virulence proteins for host cell invasion. | 2.17 | 1 | 0 | | |
dacarbazine (E)-dacarbazine : A dacarbazine in which the N=N double bond adopts a trans-configuration. | 2.57 | 2 | 0 | dacarbazine | |
leptin Leptin: A 16-kDa peptide hormone secreted from WHITE ADIPOCYTES. Leptin serves as a feedback signal from fat cells to the CENTRAL NERVOUS SYSTEM in regulation of food intake, energy balance, and fat storage. | 2.13 | 1 | 0 | | |
pyrimidinones Pyrimidinones: Heterocyclic compounds known as 2-pyrimidones (or 2-hydroxypyrimidines) and 4-pyrimidones (or 4-hydroxypyrimidines) with the general formula C4H4N2O. | 3.23 | 1 | 0 | | |
