Development of a Highly Potent D2/D3 Agonist and a Partial Agonist from Structure-Activity Relationship Study of N6-(2-(4-(1H-Indol-5-yl)piperazin-1-yl)ethyl)-N6-propyl-4,5,6,7-tetrahydrobenzo[d]thiazole-2,6-diamine Analogues: Implication in the Treatment of Parkinson’s Disease was written by Das, Banibrata;Vedachalam, Seenuvasan;Luo, Dan;Antonio, Tamara;Reith, Maarten E.

The structure-activity relationship studies with N6-(2-(4-(1H-indol-5-yl)piperazin-1-yl)ethyl)-N6-propyl-4,5,6,7-tetrahydrobenzo[d]thiazole-2,6-diamine derivatives led to development of a lead compound I which exhibited very high affinity (Ki, D2 = 16.4 nM, D3 = 1.15 nM) and full agonist activity (EC50 (GTP纬S); D2 = 3.23 and D3 = 1.41 nM) at both D2 and D3 receptors. A partial agonist mol. II (EC50 (GTP纬S); D2 = 21.6 (Emax = 27%) and D3 = 10.9 nM) was also identified. In a Parkinson’s disease (PD) animal model, I was highly efficacious in reversing hypolocomotion in reserpinized rats with a long duration of action, indicating its potential as an anti-PD drug. Compound II was also able to elevate locomotor activity in the above PD animal model significantly, implying its potential application in PD therapy. Furthermore, I was shown to be neuroprotective in protecting neuronal PC12 from toxicity of 6-OHDA. This report, therefore, underpins the notion that a multifunctional drug like I might have the potential not only to ameliorate motor dysfunction in PD patients but also to modify disease progression by protecting DA neurons from progressive degeneration. In the experiment, the researchers used many compounds, for example, tert-Butyl 3-formyl-5-methoxy-1H-indole-1-carboxylate (cas: 324756-80-1Product Details of 324756-80-1).
tert-Butyl 3-formyl-5-methoxy-1H-indole-1-carboxylate (cas: 324756-80-1) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. Indole plays a fundamental role for QS in E. coli, being one of the signal molecules responsible for the transcription of a variety of genes (gabT, and tnaB ASTD). Product Details of 324756-80-1
