It is believed that HSO3- and SO32- play important roles in several physiological processes. However, probes with two-photon absorption to detect HSO3- or SO32- in living cells are still limited. Herein, a series of novel indolium derivatives (L1-L4) with an A-pi-A? structure was designed and synthesized as ratiometric probes to detect HSO3-/SO32-in vitro. L3 and L4 display a colorimetric and ratiometric fluorescence dual response to HSO3-/SO32- with a very fast (?15 s) and high specificity, as well as low detection limits (?22 nM). Furthermore, their detection is also carried out by using a two-photon excited fluorescence method. A nucleophilic addition reaction is proposed for the sensing mechanism, which is supported by MS, 1H NMR, and density functional theory (DFT) investigations. Importantly, L3 was successfully used for detecting intrinsically generated intracellular HSO3-/SO32- in cancerous cells under one- and two-photon excited fluorescence imaging.

The important role of tert-Butyl 4-(1H-indol-4-yl)piperazine-1-carboxylate

A series of monomeric zinc silylamido complexes bearing [NNNO]-type tetradentate aminophenolate ligands, LZnN(SiMe3)2 [L = {(2-R1)ArCH2N[(CH2)2R2]CH2(4-R4-6-R3)C6H2O-}, R1 = NMe2, R2 = NiPr2, R3 = R4 = Cl (1), R3 = R4 = cumyl (3); R1 = NMe2, R2 = NEt2, R3 = R4 = cumyl (2), R3 = CPh3, R4 = Me (4); R1 = NEt2, R2 = NEt2, R3 = CPh3, R4 = Me (5); R1 = NMe2, R2 = (S)-1-butylpyrrolidin-2-yl, R3 = R4 = cumyl (6), R3 = CPh3, R4 = Me (7)], have been synthesized via reactions of Zn[N(SiMe3)2]2 and 1 equiv of the corresponding aminophenols. The monomeric nature and versatile coordination patterns of these complexes in the solid state were further confirmed by X-ray diffraction studies on complexes 2, 3, 5, and 7. In complex 3, the N,N-diisopropylamino group on the pendant side arm does not coordinate to the metal center; only the remaining three donors of the aminophenolate ligand and the silylamido group interact with the zinc center. By contrast, in complexes 2, 5, and 7, the amino group of the aryl moiety does not coordinate to the metal center, while the amino group on the pendant side arm coordinates. At room temperature, the above-mentioned structural features of these complexes are retained in solution, as confirmed by 1H NMR spectroscopy. Complexes 1-7 proved to be efficient initiators for the ring-opening polymerization of rac-lactide (rac-LA) at ambient temperature, and the polymerizations were better controlled in the presence of 2-propanol. The coordination pattern of the aminophenolate ligand exerted a significant influence on the stereoselectivity of the corresponding complex toward the polymerization of rac-LA, leading to the production of heterotactic biased polylactides (PLAs) by complexes 1 and 3 (Pm = 0.40-0.46) and moderately to highly isotactic PLAs by complexes 2 and 4-7 (Pm = 0.70-0.81). Detailed kinetic investigations revealed a first-order dependence on the monomer concentration for all complexes and different orders in the initiator concentration ranging from 1.78 to 1.81. The nature of the solvent as well as the molar ratio of the zinc complex and 2-propanol also displayed certain influence on the order of rac-LA polymerization in the initiator concentration. Factional orders of 1.80, 1.38, and 1.11 were obtained by using complex 5/iPrOH (1:1) in toluene and tetrahydrofuran and complex 5/iPrOH (1:2) in toluene, respectively. On the basis of DOSY and 1H and 13C NMR studies of zinc alkoxide model complexes “LZn(OCMe2COOMe)” as well as the fractional orders of 1.78-1.81 in the initiator concentration, activation/insertion processes likely involving more than one monomeric active species were then hypothesized.

We have previously disclosed the selective ETA receptor antagonist N-(3,4-dimethyl-5-isoxazolyl)-4?-(2-oxazolyl)[1,1?- biphenyl]-2-sulfonamide (1, BMS-193884) as a clinical development candidate. Additional SAR studies at the 2?-position of 1 led to the identification of several analogues with improved binding affinity as well as selectivity for the ETA receptor. Following the discovery that a 3-amino-isoxazole group displays significantly improved metabolic stability in comparison to its 5-regioisomer, the 3-amino-isoxazole group was combined with the optimal 2?-substituent leading to 16a (BMS-207940). Compound 16a is an extremely potent (ETA Ki = 10 pM) and selective (80000-fold for ETA vs ETB) antagonist. It is also 150-fold more potent and >6-fold more selective than 1. The bioavailability of 16a was 100% in rats and the systemic clearance and volume of distribution are higher than that of 1. In rats, intravenous 16a blocks big ET pressor responses with 30-fold greater potency than 1. After oral dosing at 3 mumol/kg, 16a displays enhanced duration relative to 1.
