New research progress on 1745-07-9 in 2021. name: 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1745-07-9, molcular formula is C11H15NO2, introducing its new discovery.

Overexpression of the ATP-binding cassette (ABC) transport proteins, like ABCB1, commonly referred to as P-glycoprotein (P-gp), initiates active efflux of a broad spectrum of unrelated chemotherapeutic drugs in structure and function, leading to chemotherapy failure. A series of 2-((pyridin-4-ylmethyl)amino)nicotinamide derivatives as potent reversal agents against P-glycoprotein-mediated multidrug resistance (MDR) were designed and synthesized. The majority of target compounds displayed great reversal potency, especially 9n. In-depth studies demonstrated 9n has high potency (EC50 = 119.6 ± 6.9 nM), low cytotoxicity, and long duration (>24 h) in reversing adriamycin (ADM) resistance in K562/A02 cells. 9n also improved the effects of other cytotoxic agents related to MDR, increased accumulation of ADM, interrupted P-gp-mediated Rh123 efflux function, and suppressed P-gp ATPase activity in K562/A02 MDR cells. The Western blot analysis indicated that the MDR reversal by 9n was not due to a decrease in protein expression. Besides, the effect of CYP3A4 was not influenced by 9n, avoiding the toxicity caused by drug interactions. The study yielded 9n with superior properties compared to the classical inhibitor verapamil (VRP) and leading compound apatinib.

The main research directions are chemical synthesis, and research on the structure and performance of functional materials.In a patent, 1745-07-9, name is 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery. Application of 1745-07-9

The authors have prepared a series of tetrahydro-beta-carbolines (THbetaC), beta-carbolines (beta-C), and other nitrogen heterocycles and evaluated them in vitro with respect to their ability to bind to benzodiazepine receptors. The fully aromatic beta-C’s were more potent than their corresponding THbetaC derivatives. When substituents possessing a carbonyl (CO2Me, COCH3, CHO) were introduced at the beta-C 3-position the in vitro potency was augmented. Alcohol substituents (CH2OH, CHOHCH3) demonstrated decreased in vitro potency. The importance of the carbonyl moiety was further demonstrated when beta-carboline-3-carboxylic acid was shown to bind tighter to benzodiazepine receptors at lower pH. A lower pH increases the concentration of the acid and decreases the concentration of the anion. 3-(Hydroxymethyl)-beta-carboline, 3-formyl-beta-carboline and 3-acetyl-beta-carboline were benzodiazepine antagonists in vivo. Methyl isoquinoline-3-carboxylate also had in vitro activity. The same structure-activity relationships seen in beta-C’s were also observed for isoquinolines.
