Novel, selective indole-based ECE inhibitors: Lead optimization via solid-phase and classical synthesis

A novel class of indole-based endothelin-converting enzyme (ECE) inhibitors was identified by high throughput screening. We report systematic optimization of this compound class by means of classical and solid-phase chemistry. Optimized compounds with a bisarylamide side chain at the 2-position of the indole skeleton exhibit low-nanomolar activity on ECE.

Gold-catalyzed annulations of 1-(2,3-butadienyl)-1H-indole derivatives

Gold-ringing! Modification of the substitution at C2 drives an entirely different cyclization of N-tethered allenylindoles. An efficient cycloisomerization takes place for the case of R being hydrogen, that is, compatible with additional functional groups. A methyl at C2 precludes this possibility and launches a stepwise process that can be tuned to yield macrocyclic trimers.

A versatile synthesis of 3-substituted 4-cyano-1,2,3,4-tetrahydro-1-oxo- beta-carbolines

In a project aimed at the synthesis of analogues of the cytotoxic -carboline alkaloid bauerine C with more advantageous solubility properties, a 3-amino analogue was prepared by treating ethyl 3-(cyanomethyl)indole-2- carboxylate with ammonia. Upon addition of aldehydes or ketones to the reaction mixture, 3-substituted 4-cyano-1,2,3,4-tetrahydro-1-oxo – carbolines were obtained in a one-pot condensation. When cyclic ketones are used, the procedure allows a convenient synthesis of tetracyclic spiro compounds. Georg Thieme Verlag Stuttgart ¡¤ New York.

Influence of nitrogen sources and plant growth-promoting rhizobacteria inoculation on growth, crude fiber and nutrient uptake in squash (cucurbita moschata duchesne ex Poir.) plants

Plant growth promoting rhizobacteria (PGPR, B) have immense potential application in sustainable agriculture as ecofriendly biofertilizers and biopesticides. In this study, the effects of three nitrogen (N) sources (NO3 -, NH4 + and NO3NH4) and PGPR on growth, crude fiber and nutrient uptake were investigated in squash plants. Some growth parameters [root dry weight (RDW), shoot dry weight (SDW), total plant dry weight (PDW), number of leaves (NL), shoot length (SL), stem diameter (SD) and number of ramifications (NR)], crude fiber (cellulose content) and nutrient uptake (N, P, K, Ca, Mg, Na, Fe, Cu, Mn and Zn) were determined. Application of NO3 -, NH4 ++ or NO3NH4 singly or in combination with PGPR inoculation led to a significant increase in RDW, SDW, PDW, NL, SL, SD and NR. Na, Cu and Zn contents, on the contrary, decreased in inoculated treated plants while no significant differences were recorded in cellulose contents (CE) of leaves except in plants fed with NO3 -. The leaf CE content ranged from 12.58 to 13.67%. The plants supplied with NO3 +B, NH4 +B and NO3NH4 +B showed significantly higher plant biomass and accumulation of N, P, K and Mn concentrations in leaves compared to all other treatments. These results suggest that specific combinations of PGPR with NO3 -, NH4+ or NO3NH4 fertilizers can be considered as efficient alternative biofertilizers to improve significantly the squash growth and nutrient uptake.

Fibrinogen receptor (GPIIb-IIIa) antagonists derived from 5,6-bicyclic templates. Amidinoindoles, amidinoindazoles, and amidinobenzofurans containing the N-alpha-sulfonamide carboxylic acid function as potent platelet aggregation inhibitors

A series of highly potent and specific fibrinogen receptor antagonists have been discovered and optimized through structural modification of the novel amidinoindole and benzofuran compounds, I and II. Systematic linker optimization afforded the amidinobenzofuran-containing inhibitor 29, which displayed an IC50 value of 250 nM in platelet aggregation assays. Attempts to enhance activity by modification of the beta-position of the beta-alanyl carboxylate group of 29 had only a modest effect on inhibitory activity in aggregation assays. Analogues prepared to enhance the activity by conformational restriction were also found to be equally or less potent. In contrast, modification at the alpha-position of the beta-alanyl carboxylate group resulted in the identification of extremely potent and novel amidinobenzofuran-containing derivatives 46-49. Reexamination of 5,6-bicyclic aromatic nucleus led to the further identification of amidinoindole- and amidinoindazole-containing derivatives 53-55. These analogues, 46-49 and 53- 55, exhibited potent in vitro activity with IC50 values of 25-65 nM in platelet aggregation assays and an IC50 value of 2 nM in fibrinogen binding assays and demonstrated a selectivity of >50000-fold for GPIIb-IIIa versus the most closely related integrin, the vitronectin receptor, alpha(v)beta3.

[Omim]Cl/FeCl3-catalyzed cross-dehydrogenative-coupling of 1,4-benzoxazinones with various indoles

A novel C(sp3)?C(sp2) cross-dehydrogenative-coupling procedure was developed for the reaction of benzoxazin-2-ones with indole derivatives. Thus, ionic liquid-mediated coupling of 1,4-benzoxazinone derivatives with indoles were observed in which [Omim]Cl/FeCl3 acted as both the solvent and the catalyst. Under [Omim]Cl/FeCl3-TBHP conditions, derivatives of 1 coupled at room temperature with indoles bearing various substituents to give the target products in good yields and within 0.5?2 h time period. The procedure is relatively environmentally friendly and is applicable to several derivatives of both reactants to access the desired products.
