Organotin complexes containing carboxylate ligands with maleimide and naphthalimide derived partial structures: TrxR inhibition, cytotoxicity and activity in resistant cancer cells

Di-n-butyltin(IV) carboxylate and tri-n-butyltin(IV) carboxylate derivatives have demonstrated strong cytotoxic effects in different types of tumor cells. Complexes with carboxylate ligands that contain maleimide and naphthalimide derived partial structures were synthesized, characterized and investigated for inhibition of the tumor-relevant enzyme thioredoxin reductase and antiproliferative effects in cancer cells. The complexes were moderate inhibitors of thioredoxin reductase with activities in the micromolar range and triggered strong cytotoxic effects in MCF-7 breast cancer and HT-29 colon carcinoma cells. Interestingly, selected complexes were highly active in vincristine and daunorubicin resistant Nalm-6 cells.

A new bicyclic oxazaborines with a bridged nitrogen atom, their thermic rearrangement and fluorescence properties

Cyclic beta-enaminones bearing secondary amino group react with 4-substituted benzenediazonium tetraphenylborates in dichloromethane to form substituted bicyclic [1,3,2lambda4]oxazaborines The oxazaborines rearrange, on heating to 200 C in the absence of solvent or in DMF or DMSO, to isomeric 2H-[1,2,4,3lambda4]triazaborines. Previously prepared [1,3,2lambda4]oxazaborines derived from acyclic beta-enaminones bearing secondary amino group either did not undergo the rearrangement or with a lot of difficulties and with negligible yield. The fluorescence behaviour of the prepared triazaborines was observed. These compounds fluoresce in 2-methyltetrahydrofurane and in solid state under low temperatures.

Alkaloids with acetylcholinesterase inhibitory activity from Corydalis racemosa (Thunb.) Pers

Two new isoquinoline alkaloids (1 and 2) along with fourteen known alkaloids (3?16) were isolated from Corydalis racemosa (Thunb.) Pers. Their structures were elucidated by analyzing spectroscopic and spectrometric data (NMR, UV, IR, and MS) and comparing their spectroscopic, spectrometric and physicochemical data with the values archived in the literature. The absolute configurations of new compounds were determined via X-ray crystallographic assay and electronic circular dichroism calculations. Acetylcholinesterase (AChE) inhibitory activity of all compounds was evaluated. Compounds 5, 6, 9, 11, and 12 exhibited inhibitory activity against AChE with IC50 values ranged from 10.2 to 63.4 muM.

Optical Control of Dopamine Receptors Using a Photoswitchable Tethered Inverse Agonist

Family A G protein-coupled receptors (GPCRs) control diverse biological processes and are of great clinical relevance. Their archetype rhodopsin becomes naturally light sensitive by binding covalently to the photoswitchable tethered ligand (PTL) retinal. Other GPCRs, however, neither bind covalently to ligands nor are light sensitive. We sought to impart the logic of rhodopsin to light-insensitive Family A GPCRs in order to enable their remote control in a receptor-specific, cell-type-specific, and spatiotemporally precise manner. Dopamine receptors (DARs) are of particular interest for their roles in motor coordination, appetitive, and aversive behavior, as well as neuropsychiatric disorders such as Parkinson’s disease, schizophrenia, mood disorders, and addiction. Using an azobenzene derivative of the well-known DAR ligand 2-(N-phenethyl-N-propyl)amino-5-hydroxytetralin (PPHT), we were able to rapidly, reversibly, and selectively block dopamine D1 and D2 receptors (D1R and D2R) when the PTL was conjugated to an engineered cysteine near the dopamine binding site. Depending on the site of tethering, the ligand behaved as either a photoswitchable tethered neutral antagonist or inverse agonist. Our results indicate that DARs can be chemically engineered for selective remote control by light and provide a template for precision control of Family A GPCRs.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 25021-08-3, help many people in the next few years.SDS of cas: 25021-08-3

Effects of protopine on proliferation of cultured rabbit aortic vascular smooth muscle cells

AIM To study the effect of protopine (Pro) on proliferation of cultured rabbit aortic vascular smooth muscle cells (VSMC) induced by endothelin-1(ET) or without ET. METHODS The method of celluar culture, the number of VSMC, [3H]-TdR incorporation into DNA assay, MTT method and electronic microscopy were performed for the effect of Pro on proliferation of cultured rat vascular smooth muscle cell. RESULTS It was observed that exposure of VSMC to ET could markedly stimulate the proliferation of VSMC and increased respectively in MTT OD values and the DNA synthesis of VSMC. The concentration 1 mumol¡¤L-1, 10 mumol¡¤L-1, 100 mumol¡¤L-1 of Pro significantly decreased the number of VSMC, the absorbance (A) of MTT and [3H]-TdR incorporation induced by ET-1 (P < 0.01 or P < 0.05). While the proliferation of normal VSMC was decreased only by the concentration 10 mumol¡¤L-1, 100 mumol¡¤L-1 of Pro, and the inhibition rate is lower than ET group's. Furthermore, Pro could antagonize morphological changes of VSMC. CONCLUSION Pro has an effective inhibition on VSMC proliferation induced by ET-1 or without ET-1, and the inhibition rate increased by Pro concentration rising and time passing by. Furthermore, the inhibition of Pro to the proliferation of VSMC is more significantly induced by ET than treated without ET. This suggests that Pro could be of interest to prevent and cure arteriosclerosis clinically. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 1081-17-0, you can also check out more blogs about1081-17-0

Carboranes as Aryl Mimetics in Catalysis: A Highly Active Zwitterionic NHC-Precatalyst

Modern catalysis takes advantage of aryl-based interactions to tune and control reactions. In the design of N-heterocyclic-carbene catalysts, both the electronic and steric nature of the nitrogen substituents play a crucial role. Although hydrocarbon-based systems and especially aryl residues have contributed considerably to overcome multifaceted catalytic challenges, the unique properties of carborane moieties, including delocalized charge, potential planar chirality, and well-known thermodynamic stability, offer unprecedented opportunities to develop new catalysts while being employed as aryl mimetics. We report a straightforward synthetic route to a novel zwitterionic triazolium-based N-heterocyclic carbene (NHC) precatalyst bearing a 7,8-dicarba-nido-undecaboranyl substituent. The catalyst’s excellent activity and its broad applicability are demonstrated in a wide range of organocatalytic transformations. Comparison of the performance with known N-aryl NHC catalysts offers preliminary insights into the stereoelectronic nature of this nido-carboranyl substituent.

Impact of type III secretion effectors and of phenoxyacetamide inhibitors of type III secretion on abscess formation in a mouse model of pseudomonas aeruginosa infection

Pseudomonas aeruginosa is a leading cause of intra-abdominal infections, wound infections, and community-acquired folliculitis, each of which may involve macro- or microabscess formation. The rising incidence of multidrug resistance among P. aeruginosa isolates has increased both the economic burden and the morbidity and mortality associated with P. aeruginosa disease and necessitates a search for novel therapeutics. Previous work from our group detailed novel phenoxyacetamide inhibitors that block type III secretion and injection into host cells in vitro. In this study, we used a mouse model of P. aeruginosa abscess formation to test the in vivo efficacy of these compounds against the P. aeruginosa type III secretion system (T3SS). Bacteria used the T3SS to intoxicate infiltrating neutrophils to establish abscesses. Despite this antagonism, sufficient numbers of functioning neutrophils remained for proper containment of the abscesses, as neutrophil depletion resulted in an increased abscess size, the formation of dermonecrotic lesions on the skin, and the dissemination of P. aeruginosa to internal organs. Consistent with the specificity of the T3SS-neutrophil interaction, P. aeruginosa bacteria lacking a functional T3SS were fully capable of causing abscesses in a neutropenic host. Phenoxyacetamide inhibitors attenuated abscess formation and aided in the immune clearance of the bacteria. Finally, a P. aeruginosa strain resistant to the phenoxyacetamide compound was fully capable of causing abscess formation even in the presence of the T3SS inhibitors. Together, our results further define the role of type III secretion in murine abscess formation and demonstrate the in vivo efficacy of phenoxyacetamide inhibitors in P. aeruginosa infection.

alpha-Pyrrolyl dipyrrins as suitable ligands for coordination chemistry

alpha-Pyrrole substituted dipyrrins (alpha-pyrrolyl dipyrrins) which belong to the family of natural products known as prodigiosins possess potent immunosuppressive, antimicrobial, antimalarial and cytotoxic properties. These tripyrrolic prodigiosin types of systems have attracted attention as versatile ligands for boron and for metals to form complexes which possess interesting properties and biological activity. The pyrrolyl dipyrrin is dianionic and can act as either bidentate or tridentate ligand to form complexes. In this review, we described rational routes to prepare alpha-pyrrolyl dipyrrin ligands and their use in the formation of metal and BF2-complexes. The alpha-pyrrolyl dipyrrins bound to metals either via two dipyrromethene pyrrole nitrogens or using all three pyrrolic nitrogens depending on the type of metal ion. However, the pyrrolyl dipyrrins act as bidentate ligands to form highly fluorescent BF2-complexes of pyrrolyl dipyrrins (3-pyrrolyl BODIPYs). The appended pyrrole ring in 3-pyrrolyl BODIPYs was functionalized with a wide range of functional groups and the functionalized 3-pyrrolyl BODIPYs were subsequently used to construct several novel 3-pyrrolyl BODIPY based fluorescent systems and conjugates. The structural, spectral and electrochemical properties of a variety of 3-pyrrolyl BODIPY based fluorescent systems and their conjugates are discussed in this review.
