Oxidative stress and polyol pathway hypotheses are generally accepted in the etiology of diabetic complications. Recently, novel carboxymethylated pyridoindoles, structural analogues of the efficient chain-breaking antioxidant stobadine, were designed, synthesised and characterised as prospective aldose reductase inhibitors endowed with antioxidant activity. Of them (2-benzyl-2,3,4,5-tetrahydro...
A series of experiments examined the ability of dopamine D3/D2 receptor agonists [(+)-(4aR,10bR)-3,4,4a,10b-tetrahydro-4-propyl-2H,5H-[1]b enzopyrano-[4,3-b]-1,4-oxazin-9-ol hydrochloride (PD 128,907), (+/-)-7-hydroxy-dipropylaminotetralin hydrobromide (7-OH-DPAT), quinpirole and bromocriptine] to produce a variety of dopaminergically mediated behaviors. The effects of these drugs with selectiv...
Evidence suggests a critical role for dopamine in the reinforcing effects of cocaine in rats and primates. However, self-administration has been less often studied in the mouse species, and, to date, "knock-out" of individual dopamine-related genes in mice has not been reported to reduce the reinforcing effects of cocaine. We studied the dopamine D1 receptor and cocaine self-administration in m...
Much data in the literature suggest a role for protein kinase C (PKC) in regulating keratinocyte proliferation and differentiation. Nevertheless, the exact role of this family of isoenzymes is unclear, since PKC agonists (e.g., phorbol esters) are known to stimulate expression of both proliferative and differentiative markers in keratinocytes. Similarly, PKC inhibitors have been demonstrated bo...
Dopamine modulates prefrontal cortex excitability in complex ways. Dopamine's net effect on local neuronal networks is therefore difficult to predict based on studies on pharmacologically isolated excitatory or inhibitory connections. In the present work, we have studied the effects of dopamine on evoked activity in acute rat brain slices when both excitation and inhibition are intact. Whole ce...
Dopamine release can regulate striatal acetylcholine efflux in vivo through at least two receptor mechanisms: (1) direct inhibition by dopamine D2 receptors on the cholinergic neurons, and (2) excitation initiated by dopamine D1 receptors. The neuroanatomical locus of the latter population of D1 receptors and the pathway(s) involved in the expression of their influence are controversial issues....
The goal of this study is to identify a novel inhibitor with anti-inflammatory and antiproliferative properties for the treatment of psoriasis. Compound f152A1 [(3S,5Z,8S,11E)-8,9,16-trihydroxy-14-methoxy-3-methyl-3,4,9,10-tetrahydro-1H-benzo[c][1]oxacyclotetradecine1,7(8H)-dione] was identified as the main active metabolite with strong inhibitory activity against tumor necrosis factor-alpha (T...
