The present invention relates to 1-methylpyrazole-piperazine compounds having dual pharmacological activity towards both the sigma (σ) receptor, and the μ-opiod receptor, to processes of preparation of such compounds, to pharmaceutical compositions comprising them, and to their use in therapy, in particular for the treatment of pain.
small-molecule inhibitors of the PD-1/PD-L1 pathway have been reported, no small-molecule inhibitors have been approved for cancer treatment. In this work, a series of novel benzamide derivatives were designed, synthesized, and evaluated to find effective inhibitors of the PD-1/PD-L1 interaction. The most potent compound D2 exhibited better activity than that of BMS202, with an IC50 of 16.17 nM. D2 could

The present invention refers to new classes of polymerisable monomers, to molecularly imprinted polymers obtainable by polymerisation of at least one of the monomers and a crosslinking monomer in the presence of a template molecule. The obtained polymers may be used for separation of enantiomers, diastereomers of the template molecule, and also for separation of the template molecule or template molecule analogues from structurally related compounds.

Synthesis of (<i>E</i>)-8-(3-Chlorostyryl)caffeine Analogues Leading to 9-Deazaxanthine Derivatives as Dual A<sub>2A</sub> Antagonists/MAO-B Inhibitors
A systematic modification of the caffeinyl core and substituents of the reference compound (E)-8-(3-chlorostyryl)caffeine led to the 9-deazaxanthine derivative (E)-6-(4-chlorostyryl)-1,3,5,=trimethyl-1H-pyrrolo[3,2-d]pyrimidine-2,4-(3H,5H)-dione (17f), which acts as a dual human A(2a) antagonist/MAO-B inhibitor (K-i(A(2A)) = 260 nM; IC50(MAO-B) = 200 nM; IC50(MAO-A) = 10 mu M) and dose dependently counteracts haloperidol-induced catalepsy in mice from 30 mg/kg by the oral route. The compound is the best balanced A(2A) antagonist/MAO-B inhibitor reported to date, and it could be considered as a new lead in the field of anti-Parkinson's agents. A number of analogues of 17f were synthesized and qualitative SARs are discussed. Two analogues of 17f, namely 18b and 19a, inhibit MAO-B with IC50 of 68 and 48 nM, respectively, being 5-7-fold more potent than the prototypical MAO-B inhibitor deprenyl (IC50 = 334 nM).
