General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

The effect of ipsapirone and S(-)-pindolol on dopamine release in rat striatum and nucleus accumbens.[Pubmed:10526141]

Brain Res. 1999 Sep 25;842(2):445-51.

Serotonin (5-hydroxytryptamine, 5-HT)(1A) receptor agonism and 5-HT(2A) receptor antagonism are components in the action of some of the recently developed antipsychotic drugs, e.g., clozapine and ziprasidone. However, studies of the role of 5-HT(1A) receptor agonism in the ability of these drugs to modulate dopamine (DA) release in the nucleus accumbens (NAC), which may be relevant to antipsychotic action, are lacking. Thus, we examined the effect of clinically available agents, ipsapirone, a 5-HT(1A) receptor partial agonist, and the mixed 5-HT(1A/1B)/beta receptor antagonist S(-)-pindolol, on DA release in the NAC compared to the striatum (STR). Ipsapirone produced a biphasic effect; low dose (0.1 mg/kg) decreased, high dose (3 mg/kg) increased and intermediate doses (0.1 and 1 mg/kg) did not change DA release in the NAC, respectively. However, ipsapirone, at all doses (0.3, 1, 3, but not 0.1 mg/kg) increased striatal DA release. S(-)-pindolol (3, 10, but not 1 mg/kg) produced a comparable increase in DA release in the NAC and STR. These results suggest that the ability of lower dose of ipsapirone to decrease DA release in the NAC is more likely to be due to 5-HT(1A) receptor agonism. On the other hand, the effect of higher dose of ipsapirone on striatal DA release may be due to 5-HT(1A) receptor antagonism, as is the case with S(-)-pindolol. The mechanism and clinical significance of these results for developing antipsychotic drugs is discussed.

Beta 1- and beta 2-adrenoceptor affinity and stimulatory effects of (S)-pindolol and iodinated (S)-pindolol.[Pubmed:2883645]

Pharmacol Toxicol. 1987 Feb;60(2):120-4.

The beta 1- and beta 2-adrenoceptor affinity and stimulatory effects of iodinated (S)-pindolol (IPIN) and (S)-pindolol were investigated in vitro using beta-adrenoceptor binding technique and isolated right atrium (rate increase, beta 1) and uterus (relaxation, beta 2) of the rat. IPIN had a higher affinity towards beta-adrenoceptors compared to (S)-pindolol, with some beta 2-adrenoceptor selectivity. In the rat uterus, IPIN produced only marginal stimulatory effects, while (S)-pindolol caused a concentration-dependent relaxation with a maximal effect that was 55% of that generated by isoprenaline. In the right atrium IPIN caused an increase in the atrial rate similar to that caused by (S)-pindolol. The concentration of IPIN required in the right atrium for a half-maximal response (pD2 = 7.81) was markedly greater than that required for occupation of half the beta-adrenoceptor population (pKB = 9.81). The beta 1-selective blocker metoprolol antagonized the effect of (S)-pindolol and IPIN on the atrial rate but a greater concentration of metoprolol (5 X 10(-6) M compared with 5 X 10(-7) M) was required to antagonize the effect of IPIN significantly. It is concluded that iodination of (S)-pindolol increased its affinity and decreased its efficacy towards beta-adrenoceptors.
