Cationic and non-peptide small molecules containing a total of six positive charges arranged on one side and a long aliphatic tail on the other have been synthesized and tested against Gram-positive and Gram-negative bacteria. The positive charges have be

New series of polyphenols with a hydrophilic galloyl-based head and a hydrophobic N-acyl tail, linked through a serinol moiety, have been synthesized and tested against colon cancer cell growth. Our structure activity relationship studies revealed that galloyl moieties are essential for growth inhibition. Moreover, the length of the N-acyl chain is crucial for the activity. Introduction of a (Z) double bond in the acyl chain increased the anticancer properties. Our findings demonstrate that 16, the most potent compound within this series, has inhibitory effects on colon cancer cell growth and metabolism (glycolysis and mitochondrial respiration) at the same time that it activates 59AMP-activated kinase (AMPK) and induces apoptotic cell death. Based on these results, we propose that 16 might reprogram colon cancer cell metabolism through AMPK activation. This might lead to alterations on cancer cell bioenergy compromising cancer cell viability. Importantly, these antiproliferative and proapoptotic effects are selective for cancer cells. Accordingly, these results indicate that 16, with an unsaturated C18 chain, might be a useful prototype for the development of novel colon cancer cell growth inhibitors affecting cell metabolism.

A series of novel lipids with designed functionalities were synthesized. These lipids are based on conjugation of α-amino acids and their esters, cationic, anionic, neutral, and photochromic moieties to the lipophilic 9-cis octadecenyl chains by amide, ester, thioester, or amine bonds. Because of the plasticity of lipidic cubic phases, it is envisaged that when mixed with monooleoyl-rac-glycerol (monoolein, MO) and water at appropriate proportions, they would assemble to form bicontinuous lipidic cubic phases (LCPs) that exhibit the well-known material properties of LCPs such as phase stability, optical transparency, and chemical permeability. Moreover, due to the nature and position of the functionality at the headgroup region, we envision them to perform as functional materials by design.

Page/Page column 24, (2008/12/04)
The present invention provides compositions and methods for human neural cell production. More particularly, the present invention provides cellular differentiation methods employing amphiphilic lipid compounds, preferably ceramide analogs of the β-hydroxyalkylamine type and optionally employing an essentially serum free MEDII conditioned medium for the generation of human neural cells from pluripotent human cells. The methods alternatively comprise modulating apoptosis by modifying the levels of PAR-4, with or without the presence of amphiphilic lipid compounds and optionally employing MEDII conditioned medium. The methods alternatively encompass modulating apoptosis by modulating the intracellular concentration of endogenous lipid second messengers, such as ceramide.
