Alkaloids induce programmed cell death in bloodstream forms of trypanosomes (Trypanosoma b. brucei)

The potential induction of a programmed cell death (PCD) in Trypanosoma b. brucei by 55 alkaloids of the quinoline, quinolizidine, isoquinoline, indole, terpene, tropane, steroid, and piperidine type was studied by measuring DNA fragmentation and changes in mitochondrial membrane potential. For comparison, the induction of apoptosis by the same alkaloids in human leukemia cells (Jurkat APO-S) was tested. Several alkaloids of the isoquinoline, quinoline, indole and steroidal type (berberine, chelerythrine, emetine, sanguinarine, quinine, ajmalicine, ergotamine, harmine, vinblastine, vincristine, colchicine, chaconine, demissidine and veratridine) induced programmed cell death, whereas quinolizidine, tropane, terpene and piperidine alkaloids were mostly inactive. Effective PCD induction (EC50 below 10 muM) was caused in T. brucei by chelerythrine, emetine, sanguinarine, and chaconine. The active alkaloids can be characterized by their general property to inhibit protein biosynthesis, to intercalate DNA, to disturb membrane fluidity or to inhibit microtubule formation.

Study of reactions of lactim ethers with cyanoacetohydrazide

Main pathways in reactions of lactim ethers with cyanoacetic acid hydrazide depend on the ring size of the starting lactim ether. Five-membered O-methylbutyrolactim produces pre-dominantly 3-amino-4-(pyrrolidin-2-ylidene)-4, 5-dihydropyrazol-5-one, whereas condensation of six-and seven-membered lactim ethers (O-methylvalero-and O-methylcaprolactim, respectively) affords the corresponding polymethylenetriazoles as the major products.

Synthesis and in vitro evaluation of N-substituted maleimide derivatives as selective monoglyceride lipase inhibitors

The endocannabinoid 2-arachidonoylglycerol (2-AG) plays a major role in many physiological processes, and its action is quickly terminated via enzymatic hydrolysis catalyzed by monoglyceride lipase (MGL). Regulating its endogenous level could offer therapeutic opportunities; however, few selective MGL inhibitors have been described so far. Here, we describe the synthesis of N-substituted maleimides and their pharmacological evaluation on the recombinant human fatty acid amide hydrolase (FAAH) and on the purified human MGL. A few N-arylmaleimides were previously described (Saario, S. M.; Salo, O. M.; Nevalainen, T.; Poso, A.; Laitinen, J. T.; Jarvinen, T.; Niemi, R. Characterization of the Sulfhydryl-Sensitive Site in the Enzyme Responsible for Hydrolysis of 2-Arachidonoylglycerol in Rat Cerebellar Membranes. Chem. Biol. 2005, 12, 649-656) as MGL inhibitors, and along these lines, we present a new set of maleimide derivatives that showed low micromolar IC50 and high selectivity toward MGL vs FAAH. Then, structure-activity relationships have been investigated and, for instance, 1-biphenyl-4-ylmethylmaleimide inhibits MGL with an IC50 value of 790 nM. Furthermore, rapid dilution experiments reveal that these compounds act as irreversible inhibitors. In conclusion, N-substituted maleimides constitute a promising class of potent and selective MGL inhibitors.

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

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.

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.

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.

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.
