A semisynthetic approach to novel lipid A derivatives from Escherichia coli (E. coli) lipid A is reported. This methodology stands as an alternative to common approaches based exclusively on either total synthesis or extraction from bacterial sources. It relies upon the purification of the lipid A fraction from fed-batch fermentation of E. coli, followed by(More)
The over-expression of human neuroglobin (NGB), a heme-protein preferentially expressed in the brain, displays anti-apoptotic effects against hypoxic/ischemic and oxidative stresses enhancing neuron survival. As hypoxic and oxidative stress injury frequently occurs in fast proliferating neoplastic tissues, here, the effect of these stressors on the level,(More)
Lipid A is the lipophilic region of lipopolysaccharides and lipooligosaccharides, the major components of the outer leaflet of most part of Gram-negative bacteria. Some lipid As are very promising immunoadjuvants. They are obtained by extraction from bacterial cells or through total chemical synthesis. A novel, semisynthetic approach to lipid As is ongoing(More)
Although paclitaxel (Taxol) is an active chemotherapeutic agent for the treatment of breast cancer, not all breast tumors are sensitive to this drug. In particular, there is a wide agreement on the low sensitivity of estrogen receptor (ER) α-positive breast cancer to paclitaxel treatment. However, the ERα-based insensitivity to paclitaxel is still elusive.(More)
In the year 2000, the third member of the globin family was discovered in human and mouse brain and named neuroglobin (Ngb). Neuroglobin overexpression significantly protects both heart and brain from hypoxic/ischemic and oxidative stress-related insults, whereas decreased Ngb levels lead to an exacerbation of tissue injuries. Moreover, Ngb overexpression(More)
