Euphorbia factor L-3, a lathyrane diterpenoid extracted from Euphorbia lathyris, was found to display good anti-inflammatory activity with very low cytotoxicity. To find more potent anti-inflammatory drugs, two series of Euphorbia factor L-3 derivatives with fatty and aromatic acids were designed and synthesized. Among them, lathyrane derivative 5n exhibited most potent inhibition on LPS-induced NO production in RAW264.7 cells with no obvious cytotoxicity. To determine the key characteristics of Euphorbia factor L-3 derivatives that contribute to anti-inflammatory activity, we conducted a structure-activity relationship study of these compounds.

The ability to selectively forge C-heteroatom bonds by C-F scission is typically accomplished by metal catalysts, specialized ligands and/or harsh reaction conditions. Described herein is a base-mediated defluorosilylation of unactivated C(sp(2))-F and C(sp(3))-F bonds that obviates the need for metal catalysts. This protocol is characterized by its simplicity, mild reaction conditions, and wide scope, even within the context of late-stage functionalization, constituting a complementary approach to existing C-Si bond-forming protocols.

Diabetes is one of the pre-dominant metabolic disorders all over the world. It is the prime reason of mortality and morbidity due to hyperglycemia which is link with numerus obstacles. Delaying absorption and digestion of carbohydrate has great therapeutic impact for governing postprandial hyperglycemia. Consequently, alpha glucosidase is one of the potential therapeutic approaches that reduce absorption of glucose and delay carbohydrate digestion hence maintaining blood glucose level. In this regard we have synthesized benzothiazole based oxadiazole in search of potent anti-diabetic agent as a-glucosidase Inhibitors. Benzothiazole based oxadiazole derivatives 1-23 have been synthesized, characterized by (INMR)-I-1, (CNMR)-C-13, and MS and evaluated for alpha-glucosidase Inhibition. All analogs exhibited a varying degree of alpha-glucosidase inhibitory activity with IC50 values ranging in between 0.5 +/- 0.01-30.90 +/- 0.70 mu M when compared with the standard acarbose (IC50 = 866.30 +/- 3.20 mu M). Structure activity relationship has been established for all compounds. Molecular docking studies were performed to predict the binding interaction of the compounds with the active site of enzyme.

Assessment of ocular irritation risk is an international regulatory requirement in the safety evaluation of products. In response to this need, L’Oreal developed the SkinEthie Human Corneal Epithelium (HCE) Eye Irritation Test (Err) that has been included in OECD Test Guideline 492. SkinEthic (TM) HCE EIT is able to correctly and reliably identify chemicals not requiring classification versus labelling for eye irritation or serious eye damage according to UN GHS. In an effort to promote its global use, the performance of the method was evaluated after long-distance shipment and compared to European shipment conditions. Results obtained by Cosmos Technical Center (Japan) after extended tissues transit were compared to results obtained in L’Oreal (France). Thirty-nine out of 40 blinded chemicals, representing different functional chemical classes, were consistently classified in both laboratories. The SkinEthic (TM) HCE EIT test method was also evaluated for its performance after extended storage of the tissues. The performance was in agreement with the values reported in OECD TG 492, with an overall accuracy of 87.1% (based on 119 chemicals), sensitivity of 95.5% and specificity of 73.5%. The reliability and relevance of SkinEthic (TM) HCE Err test method after long-distance shipment and extended storage remain in agreement with regulatory validation criteria.

Palladium-catalyzed cross-coupling reactions between carboxylic acids and aryl halides have several possible competitive pathways. Decarboxylative C-C bond coupling and C-H arylation are well established in the literature. However, direct C-O bond coupling between carboxylic acids and aryl halides has received little success. In this report, we describe a protocol for exclusive C-O bond formation, enabled by a bidentate N,N-ligand such as 1,10-phenanthroline. The reaction is general for a broad range of carboxylic acids and iodoarenes. Experimental evidence and computational results suggest a high energy barrier for the alternative pathway of decarboxylative carbon-carbon bond coupling.

N-Acylpyrrole-type amides are a class of versatile building blocks in asymmetric synthesis. We report that by employing Ni(COD)(2)/2,2 ‘-bipyridine (5 mol%) catalytic system, the direct, catalytic alcoholysis of N-acylpyrrole-type aromatic and aliphatic amides with both primary and secondary alcohols can be achieved efficiently under very mild conditions (rt, 1 h) even at gram scale. By increasing the catalyst loading to 10 mol%, prolonging reaction time (18 h), and/or elevating reaction temperature to 50 degrees C/80 degrees C, the reaction could be extended to both complex and hindered N-acylpyrroles as well as to N-acylpyrazoles, Nacylindoles, and to other (functionalized) primary and secondary alcohols. In all cases, only 1.5 equiv. of alcohol were used. The value of the method has been demonstrated by the racemization-free, catalytic alcoholysis of chiral amides yielded from other asymmetric methodologies.

(-)-5-Hydroxygoniothalamin, (-)-5-acetylgoniothalamin, and (+)-5-hydroxygoniothalamin, isolated from the Goniothalamus genus, are synthesized from triacetyl-O-D-glucal by employing the Ferrier reaction, Mitsunobu reaction, and Jones oxidation as key steps. The synthetic procedure also yields the epimers of (-)-5-hydroxygoniothalamin and (+)-5-hydroxygoniothalamin employing acid-mediated transition-metal-free epimerization at C-5 of styryllactones. Further studies reveal that the epimerization is facilitated by the phenyl group present on the styryllactones. Also, depending on the dihydroxylation reaction conditions, various analogues of saturated styryllactones are synthesized utilizing oxa-Michael reaction conditions.

A site-selective supported palladium nanoparticle catalyzed Suzuki-Miyaura cross-coupling reaction with heteroaryl esters and arylboronic acids as coupling partners was developed. This methodology provides a heterogeneous catalytic route for aryl ketone formation via C(acyl)-O bond activation of esters by successful suppression of the undesired decarbonylation phenomenon. The catalyst can be reused and shows high activity after eight cycles. The XPS analysis of the catalyst before and after the reaction suggested that the reaction might be performed via a Pd-0/Pd-II catalytic cycle that began with Pd-0.

Cancer is a leading cause of human mortality around the globe. In this study, mechanism-based SAR (Structure Activity Relationship) was employed to investigate the carcinogenicity of aromatic amines and nitroaromatics based on CPDB. Principal component analysis and cluster analysis were used to construct the SAR model. Principle component analysis generated three principal components from 12 mechanism-based descriptors. The extracted principal components were later used for cluster analysis, which divided the selected 55 chemicals into six clusters. The three principal components were proposed to describe the transport, reactivity and electrophilicity properties of the chemicals. Cluster analysis indicated that the relevant transport properties positively correlated with the carcinogenic potential and were contributing factors in determining the cardnogenicity of the studied chemicals. The mechanism-based SAR analysis suggested the electron donating groups, electron withdrawing groups and planarity are significant factors in determining the carcinogenic potency for studied aromatic compounds. The present study may provide insights into the relationship between the three proposed properties and the carcinogenesis of aromatic amines and nitroaromatics.
