Marine organisms are recognized as a source of compounds with interesting biological activities. Vibrio neocaledonicus has been reported on for its high effectiveness against corrosion in metals but it has been little studied for its chemical and biological activities. In this study, four compounds were isolated from V. neocaledonicus: indole (1); 1H-indole-3-carboxaldehyde (2); 4-hydroxybenzaldehyde (3) and Cyclo (-Pro-Tyr) (4); using a bioassay-guided method, since in a previous study it was found that the ethyl acetate extract was active on the enzymes acetylcholinesterase (AChE), alpha-glucosidase (AG) and xanthine oxidase (XO). The inhibitory activities of the three compounds against AChE, AG and XO was also evaluated. In addition, the enzymatic inhibitory activity of indole to the toxins from the venom of Bothrops asper was tested. Results showed that indole exhibited strong inhibitory activity to AG (IC50 = 18.65 +/- 1.1 mu M), to AChE, and XO (51.3% and 44.3% at 50 mu g/mL, respectively). 1H-indole-3-carboxaldehyde displayed strong activity to XO (IC50 = 13.36 +/- 0.39 mu M). 4-hydroxybenzaldehyde showed moderate activity to XO (50.75% at 50 mu g/mL) and weak activity to AChE (25.7% at 50 mu g/mL). Furthermore, indole showed a significant in vitro inhibition to the coagulant effect induced by 1.0 mu g of venom. The findings were supported by molecular docking. This is the first comprehensive report on the chemistry of V. neocaledonicus and the bioactivity of its metabolites.

Aiming at generating a series of monoterpene indole alkaloids with enhanced multidrug resistance (MDR) reversing activity in cancer, two major epimeric alkaloids isolated from Tabernaemontana elegans, tabernaemontanine (1) and dregamine (2), were derivatized by alkylation of the indole nitrogen. Twenty-six new derivatives (3-28) were prepared by reaction with different aliphatic and aromatic halides, whose structures were elucidated mainly by NMR, including 2D NMR experiments. Their MDR reversal ability was evaluated through a functional assay, using as models resistant human colon adenocarcinoma and human ABCB1-gene transfected L5178Y mouse lymphoma cells, overexpressing P-glycoprotein (P-gp), by flow cytometry. A considerable increase of activity was found for most of the derivatives, being the strongest P-gp inhibitors those sharing N-phenethyl moieties, displaying outstanding inhibitory activity, associated with weak cytotoxicity. Chemosensitivity assays were also performed in a model of combination chemotherapy in the same cell lines, by studying the in vitro interactions between the compounds and the antineoplastic drug doxorubicin. Most of the compounds have shown strong synergistic interactions with doxorubicin, highlighting their potential as MDR reversers. QSAR models were also explored for insights on drug-receptor interaction, and it was found that lipophilicity and bulkiness features were associated with inhibitory activity, although linear correlations were not observed.

Salmonellosis in poultry is an important disease that seriously impedes the development of the poultry industry. The increased resistance to antimicrobials against Salmonella has been a major public health concern worldwide. We conducted a study from January to June 2016 in and around the Rajshahi district of Bangladesh on the commercial chicken to isolate, identify and characterize poultry-specific Salmonella, to assess the potential risk factors and to determine the antimicrobial resistance pattern of the isolates. The overall prevalence of Salmonella enterica was 41% (49/120) [95% CI: 31.95%-50.17%] with 41.7% in broiler chicken (25/60) [95% CI: 29.06%-55.12%] and 40% in layer chicken (24/60, 40%) [95% CI: 27.56%-53.46%]. Samples collected from Rajshahi city (OR = 1.37, 95% CI: 0.50-3.73) and Puthia Upazila (OR = 1.51, 95% CI: 0.56-4.12) were more likely to be positive for Salmonella than Charghat Upazila. Salmonella detection was 1.3 times higher in chicken, providing loose feed than those provided ready feed. All the isolates fermented dextrose, maltose and mannitol with the production of acid and gas, but did not ferment sucrose and lactose. The isolates showed catalase, MR, citrate utilization test and TSI agar test positive, but indole and V-P tests negative. Salmonella isolates were sensitive to ciprofloxacin (90%), gentamycin (80%), amoxicillin (75%), streptomycin (70%), ampicillin (45%) and sulfamethoxazole-trimethoprim (45%), whereas highly resistant to penicillin (100%) and nalidixic acid (100%) followed by sulfamethoxazole-trimethoprim (55%), ampicillin (40%) and amoxicillin (25%). Salmonella enterica is endemic in commercial chicken production in Bangladesh with high prevalence. A considerable proportion of Salmonella isolates was found to be resistant to the majority of the common antimicrobial drugs. A good biosecurity system could be effective for the reduction of Salmonella. It is necessary to obtain universal commitments to establish prudent antibiotic use policies.

In an article, author is Song Chunlan, once mentioned the application of 69-79-4, Name: Maltose, Name is Maltose, molecular formula is C12H22O11, molecular weight is 342.2965, MDL number is MFCD00135877, category is indole-building-block. Now introduce a scientific discovery about this category.

Dearomative annulation of indoles has emerged as a powerful tool for the preparation of polycyclic indoline-based alkaloids. Compared with well-established methods towards five-membered-ring-fused indolines, the six-membered-ring-fused indolines are rarely accessed under thermal conditions. Herein, a dearomative [4+2] annulation between different indoles is developed through an electrochemical pathway. This transformation offers a remarkably regio- and stereoselective route to highly functionalized pyrimido[5,4-b]indoles under oxidant- and metal-free conditions. Notably, this electrochemical approach maintains excellent functional-group tolerance and can be extended as a modification tactic for pharmaceutical research. Preliminary mechanism studies indicate that the electrooxidation annulation proceeds through radical-radical cross-coupling between an indole radical cation and an N-centered radical generated in situ.

Modification of Bischler-Mohlau indole derivatives through palladium catalyzed Suzuki reaction as effective cholinesterase inhibitors, their kinetic and molecular docking studies

Due to the immense importance of aryl indole nucleus, herein we report the palladium-catalyzed arylation of N-substituted 2-aryl indole utilizing Suzuki-Miyaura cross coupling methodology. The biological screening for cholinesterase inhibition of the resulted biaryl indole moieties was carried out to evaluate their pharmacological potential, expecting to involve the development of new therapeutics for various inflammatory, cardiovascular, gastrointestinal and neurological diseases. This research work also involved the use of utilization of microwave-assisted organic synthesis (MAOS) for the synthesis of Bischler-Mohlau indole which is further biarylated via palladium-catalyzed cross coupling reaction. All the synthetic compounds (3a-n) were tested for cholinesterase inhibition and exhibited high level of AChE inhibitory activities. Interestingly, compounds 3m and 3n were found to be dual inhibitors, however, remaining compound exhibited no inhibitory activity against BChE. The biological potential of the resulted compounds was explained on the basis of molecular docking studies, performed against AChE and BChE, exploring the probable binding modes of most potent inhibitors.

Bronsted Acid-Catalyzed Cyclopropanation of Indoles Using alpha-Aryl-alpha-diazoacetates

Metal-free cyclopropanation of N-protected indoles with alpha-aryl-alpha-diazoacetates proceeded by using a catalytic amount of triflic imide as a Bronsted acid catalyst. The use of a catalytic amount of methyl phenylacetate improved the efficiency of the Bronsted acid-catalyzed cyclopropanation. A reaction mechanism including C-protonation of diazoacetates with HNTf2, followed by formal [3+2] cycloaddition with indoles and 1,3-rearrangement was proposed for the cyclopropanation.
