There are many of pathogen parasite species with different susceptibility profile to antiparasitic drugs. Unfortunately, almost QSAR models predict the biological activity of drugs against only one parasite species. Consequently, predicting the probability with which a drug is active against

A range of amide derivatives of L-dopa were synthesized and investigated for their pharmacological activity and their ability to be converted to L-dopa using the unilaterally 6-hydroxydopamine (6-OHDA)-lesioned rat, as an experimental model of Parkinson's disease. The diacetyl derivative of

Preventing aberrant immune responses against the microbiota is essential for the health of the host. Microbiota-shed pathogen-associated molecular patterns translocate from the gut lumen into systemic circulation. Here, we examined the role of hemolymph (insect blood) filtration in regulating systemic

L-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesia (LID) is the most common complication of standard L-DOPA therapy for Parkinson's disease experienced by most parkinsonian patients. LID is associated with disruption of dopaminergic homeostasis in basal ganglia following L-DOPA administration. Norepinephrine (NE) is another important

Parkinson's disease (PD) is a neurological disorder characterized by degeneration of nigrostriatal dopaminergic (DAergic) system. Present treatment targeting to DAergic system solely ameliorated the symptoms but failed to retard the DAergic neuron degeneration, therefore new therapeutic methods aiming at preventing

A series of multifunctional codrugs (1-6) were synthesized to overcome the pro-oxidant effect associated with L-dopa (LD) therapy. Target compounds release LD and dopamine (DA) in human plasma after enzymatic hydrolysis, displaying an antioxidant effect superior to that of N-acetylcysteine

In advanced Parkinson's disease, l-DOPA treatment causes the appearance of abnormal involuntary movements or l-DOPA-induced dyskinesia (LID). LID results in part from l-DOPA-induced activation of extracellular signal-regulated kinase (ERK) in the dopamine-denervated striatum. Activated ERK triggers nuclear responses, including phosphorylation
