Vapor-phase alkylation of aroms. over environmentally benign solid catalysts is a valuable alternative to the conventional alkylation carried out traditionally over mineral acids and Friedel-Crafts type catalysts. Two examples for the development of new, s ...
New 2-benzylamino-3,4-dihydroxypyrrolidines bearing aromatic and aliphatic amido side chains have been prepared. The influence of the amido substituents on the inhibitory activity of these diamines toward 24 commercially available glycosidases was determin ...
The development of targeted treatment strategies adapted to individual patients requires identification of the different tumor classes according to their biology and prognosis. We focus here on the molecular aspects underlying these differences, in terms o ...
Boron neutron capture therapy (BNCT) is an experimental, binary treatment far brain cancer which requires as the first step that tumor tissue is targeted with a boron-10 containing compound. Subsequent exposure to a thermal neutron flux results in destruct ...
Refining the chemical structure of functionalized pyrrolidine-based inhibitors of Golgi α- mannosidase II (GMII) to optimize binding affinity provided a lead molecule that demonstrated nanomolar competitive inhibition of α-mannosidases II and an optimal fi ...
The DNA repair protein O6-methylguanine-DNA methyltransferase (MGMT, alkyltransferase) is an important suicide enzyme involved in defense against O6-alkylating endogenous metabolites and environmental carcinogens. It also plays a pivotal role in primary an ...
Despite aggressive surgery and post-operative radiation and chemotherapy, the prognosis is poor for glioblastoma patients. Anti-angiogenic therapy with compounds such as endostatin could delay the onset of relapse. However, the short systemic half-life of ...
New substituted pyrrolidine-3,4-diol derivatives were prepared from D-(-)- and L-(+)-phenyl glycinol. The influence of the configuration and the substitution of the lateral side chain of these derivatives on the inhibition of 25 commercial glycosidases wer ...
We present the first X-PEEM spectromicroscopy semi-quantitative data, acquired on Gd in glioblastoma cell cultures from human brain cancer. The cells were treated with a Gd compound for the optimization of GdNCT (Gadolinium Neutron Capture Therapy). We ana ...
The type beta transforming growth factors (TGF) are potent regulators of the growth and functions of lymphocytes and macrophages. Recently the human glioblastoma cell line 308 was shown to produce TGF-beta 2. The relevance of this finding was evaluated fur ...
