Cannabidiol (CBD), the main non-psychotomimetic component of the plant Cannabis sativa, exerts therapeutically promising effects on human mental health such as inhibition of psychosis, anxiety and depression. However, the mechanistic bases of CBD action are unclear. Here we investigate the potential involvement of hippocampal neurogenesis in the anxiolytic(More)
BACKGROUND Pharmacological activation of cannabinoid receptors elicits antitumoral responses in different cancer models. However, the biological role of these receptors in tumor physio-pathology is still unknown. METHODS We analyzed CB2 cannabinoid receptor protein expression in two series of 166 and 483 breast tumor samples operated in the University(More)
Alzheimer's disease (AD) is one of the most frequent causes of death and disability worldwide and has a significant clinical and socioeconomic impact. In the search for novel therapeutic strategies, serotonin 5-HT6 receptor (5-HT6R) has been proposed as a promising drug target for cognition enhancement in AD. This manuscript reviews the compelling evidence(More)
In this work, we report the design and synthesis of a set of fluorescent probes targeting the human 5-HT1A receptor (h5-HT1AR). Among the synthesized compounds, derivative 4 deserves special attention as being a high-affinity ligand (K i = 2 nM) with good fluorescent properties (I em > 1000 au and a fluorescence quantum yield, Φf, of 0.26), which enables(More)
In this work we report the synthesis of a set of labeled ligands targeting the human 5-HT(6) receptor (h5-HT(6)R). Among the synthesized compounds, fluorescent probe 10 (K(i) = 175 nM and Φ(f) = 0.21) and biotinylated derivative 15 (K(i) = 90 nM) deserve special attention because they enable direct observation of the h5-HT(6)R in cells. Thus, they represent(More)
A basal tone of the endocannabinoid 2-arachidonoylglycerol (2-AG) enhances late oligodendrocyte progenitor cell (OPC) differentiation. Here, we investigated whether endogenous 2-AG may also promote OPC proliferation in earlier stages. We found that the blockade of 2-AG synthesizing enzymes, sn-1-diacylglycerol lipases α and β (DAGLs), with RHC-80267 or the(More)
Angiogenesis is a requirement for the sustained growth and proliferation of solid tumors, and the development of new compounds that induce a sustained inhibition of the proangiogenic signaling generated by tumor hypoxia still remains as an important unmet need. In this work, we describe a new antiangiogenic compound (22) that inhibits proangiogenic(More)
We report the synthesis of new compounds 4-35 based on two different openings (A and B) of the chromane ring present in the previously identified 5-HT1A receptor (5-HT1AR) ligand 3. The synthesized compounds were assessed for binding affinity, selectivity, and functional activity at the 5-HT1AR. Selected candidates resulting from B opening were also(More)
We report the synthesis of new compounds 4-35 based on structural modifications of different moieties of previously described lead UCM-2550. The new nonpiperazine derivatives, representing second-generation agonists, were assessed for binding affinity, selectivity, and functional activity at the 5-HT(1A) receptor (5-HT(1A)R). Computational β(2)-based(More)
Cell division protein FtsZ is the organizer of the cytokinetic Z-ring in most bacteria and a target for new antibiotics. FtsZ assembles with GTP into filaments that hydrolyze the nucleotide at the association interface between monomers and then disassemble. We have replaced FtsZ's GTP with non-nucleotide synthetic inhibitors of bacterial division. We(More)
