Allosteric Modulation of the Adenosine A1 Receptor. Synthesis and Biological Evaluation of Novel 2-Amino-3-benzoylthiophenes as Allosteric Enhancers of Agonist Binding
摘要:
Novel allosteric enhancers of agonist binding to the rat adenosine Al receptor are described. The lead compound for the new series was PD 81,723 ((2-amino-4,5-dimethyl-3-thienyl)[3(trifluoromethyl)phenyl]methanone), a compound previously reported by Bruns and co-workers (Mol. Pharmacol. 1990, 38, 950-958). The 4,5-dimethyl group and the benzoyl moiety were targets for further modifications, leading to series of 4,5-dialkyl (12a-g), of tetrahydrobenzo (12h-u), and of tetrahydropyridine (13a-g) derivatives. A number of compounds, in particular 12b, 12e, 12j, 12n, and 12u, proved superior to PD 81,723, Their EC50 values for enhancing the binding of the adenosine Al receptor agonist N-6-cyclopentyladenosine to the receptor were lower, and/or their antagonistic activity on the adenosine Al receptor was shown to be diminished.

The invention relates to the use of a centrifugal contact-separator for carrying out a non-radioactive reaction in a liquid-liquid emulsion formed from two immiscible liquids. The invention also relates to a process for carrying out a reaction in a centrifugal contact-separator, and to a process for carrying out a catalytic reaction in a centrifugal contact-separator. An example of a process for carrying out a reaction, comprising the following steps: i) continuously introducing a liquid phase A and a liquid phase B into at least one first centrifugal contact separator, where in liquid phases A and B are immiscible and wherein phase A and/or phase B comprise at least one reactant ii) mixing phase A and phase B thereby allowing an emulsion to be formed iii) applying a centrifugal force that allows phase separation of the emulsion, such that phases A′ and B′ are obtained; iv) optionally, recovering a reaction product from at least one or the phases A′ and B′.
