Ziprasidone(CP88059) is a combined 5-HT (serotonin) and dopamine receptor antagonist which exhibits potent effects of antipsychotic activity.Target: 5-HT receptor; Dopamine receptorZiprasidone (hydrochloride) is the salt form of ziprasidone, which possesses an in vitro 5-HT2A/dopamine D2 receptor affinity ratio higher than any clinically available antipsychotic agent. In vivo, ziprasidone antagonizes 5-HT2A receptor-induced head twitch with 6-fold higher potency than for blockade of d-amphetamine-induced hyperactivity, a measure of central dopamine D2 receptor antagonism. Ziprasidone also has high affinity for the 5-HT1A, 5-HT1D and 5-HT2C receptor subtypes, which may further enhance its therapeutic potential [1]. Ziprasidone sulfoxide and sulfone were the major metabolites in human serum. The affinities of the sulfoxide and sulfone metabolites for 5-HT2 and D2 receptors are low with respect to ziprasidone, and are thus unlikely to contribute to its antipsychotic effects [2]. Ziprasidone was associated with significant differential adverse effects relative to placebo in BPM, BPD, and schizophrenia with no significant difference in weight gain in all 3 groups. Self-reported somnolence was increased across the 3 conditions. Subjects with BPM were more vulnerable to EPS than those with BPD or schizophrenia [3].Clinical indications: Bipolar I disorder; Bipolar disorder; Mania; SchizophreniaFDA Approved Date: February 2001

Naratriptan is a selective 5-HT1 receptor subtype agonist and is a triptan drug that is used for the treatment of migraine headaches.Target: 5-HT1 ReceptorNaratriptan is a triptan drug marketed by GlaxoSmithKline and is used for the treatment of migraine headaches. Naratriptan is available in 2.5 mg tablets. It is a selective 5-HT1 receptor subtype agonist. Naratriptan is used for the treatment of the acute migraine attacks and the symptoms of migraine, including severe, throbbing headaches that sometimes are accompanied by nausea and sensitivity to sound or light.The causes of migraine are not clearly understood; however, the efficacy of naratriptans and other triptans is believed to be due to their activity as 5HT (serotonin) agonists.A meta-analysis of 53 clinical trials has shown that all triptans are effective for treating migraine at marketed doses and that naratriptan, although less effective than sumatriptan and rizatriptan was more effective than placebo in reducing migraine symptoms at two hours and efficacy was demonstrated in almost two thirds of subjects after four hours of treatment.

At higher concentrations, JZL195 inhibited ABHD6 but not any of the other brain serine hydrolases detected in our competitive ABPP assays. JZL195 also inhibited rat and human FAAH and MAGL enzymes with IC50 values in the range of 10–100 nM based on competitive ABPP assays [1].in vivo: A time course analysis of mice given one administration ofJZL195 (20 mg/kg, i.p.) revealed that blockade of FAAH andMAGL lasted at least 10 h as judged by gel-based ABPP or AEAand 2-AG hydrolysis assays [1]. The effect of systemic injections of a range of doses of JZL195 and the pan-cannabinoid receptor agonist WIN55212 were performed 1 day following intraplantar injection of CFA in C57BL/6 mice. JZL195 and WIN55212 both reduced mechanical allodynia and thermal hyperalgesia, and produced catalepsy and sedation in a dose dependent manner. Unlike WIN55212, JZL195 reduced allodynia at doses below those at which side-effects were observed [2].

Escitalopram is a selective serotonin reuptake inhibitor (SSRI) with Ki of 0.89 nM.Target: SSRIsEscitalopram, the S-enantiomer of citalopram, belongs to a class of antidepressant agents known as selective serotonin-reuptake inhibitors (SSRIs). Escitalopram may be used to treat major depressive disorder (MDD) and generalized anxiety disorder (GAD). Escitalopram has no significant affinity for adrenergic (alpha1, alpha2, beta), cholinergic, GABA, dopaminergic, histaminergic, serotonergic (5HT1A, 5HT1B, 5HT2), or benzodiazepine receptors; antagonism of such receptors has been hypothesized to be associated with various anticholinergic, sedative, and cardiovascular effects for other psychotropic drugs. The chronic administration of escitalopram is found to downregulate brain norepinephrine receptors, as has been observed with other drugs effective in the treatment of major depressive disorder. Escitalopram does not inhibit monoamine oxidase.

Pergolide Mesylate is an antiparkinsonian agent which functions as a dopaminergic agonist.Target: Dopamine ReceptorPergolide mesylate (trade name Permax) is an ergoline-based dopamine receptor agonist used in some countries for the treatment of Parkinson's disease. Pergolide mesylate functions as an agonist at the dopamine D2, D1 and serotonin 5-HT1A, 5-HT1B, 5-HT2A, 5-HT2B, and 5-HT2C receptors. It may possess agonist activity at other dopamine receptor subtypes as well, similar to cabergoline [1, 2]. Pergolide mesylate decreases plasma prolactin concentrations [3]. The weak agonist activity of pergolide at D1 receptors somewhat alters its clinical and side effect profile in the treatment of Parkinson's disease. The drug is in decreasing use, as it is reported to be associated with a form of heart disease called cardiac fibrosis. The use of pergolide or cabergoline is associated with a significantly increased risk of newly diagnosed cardiac-valve regurgitation [4].
