Toxicity and mutagenicity of low-metallic automotive brake pad materials

Organic friction materials are standardly used in brakes of small planes, railroad vehicles, trucks and passenger cars. The growing transportation sector requires a better understanding of the negative impact related to the release of potentially hazardous materials into the environment. This includes brakes which can release enormous quantities of wear particulates. This paper addresses in vitro detection of toxic and mutagenic potency of one model and two commercially available low-metallic automotive brake pads used in passenger cars sold in the EU market. The model pad made in the laboratory was also subjected to a standardized brake dynamometer test and the generated non-airborne wear particles were also investigated. Qualitative “organic composition” was determined by GC/MS screening of dichloromethane extracts. Acute toxicity and mutagenicity of four investigated sample types were assessed in vitro by bioluminescence assay using marine bacteria Vibrio fischeri and by two bacterial bioassays i) Ames test on Salmonella typhimurium His- and ii) SOS Chromotest using Escherichia coli PQ37 strain. Screening of organic composition revealed a high variety of organic compounds present in the initial brake pads and also in the generated non-airborne wear debris. Several detected compounds are classified by IARC as possibly carcinogenic to humans, e. g. benzene derivatives. Acute toxicity bioassay revealed a response of bacterial cells after exposure to all samples used. Phenolic resin and wear debris were found to be acutely toxic; however in term of mutagenicity the response was negative. All non-friction exposed brake pad samples (a model pad and two commercial pad samples) were mutagenic with metabolic activation in vitro.

Medicinal chemistry inspired fragment-based drug discovery

Abstract Lead generation can be a very challenging phase of the drug discovery process. The two principal methods for this stage of research are blind screening and rational design. Among the rational or semirational design approaches, fragment-based drug discovery (FBDD) has emerged as a useful tool for the generation of lead structures. It is particularly powerful as a complement to high-throughput screening approaches when the latter failed to yield viable hits for further development. Engagement of medicinal chemists early in the process can accelerate the progression of FBDD efforts by incorporating drug-friendly properties in the earliest stages of the design process. Medium-chain acyl-CoA synthetase 2b and ketohexokinase are chosen as examples to illustrate the importance of close collaboration of medicinal chemists, crystallography, and modeling.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 272-16-2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 272-16-2, in my other articles.

Aerogel from chemo-enzymatically oxidized fenugreek gum: an innovative delivery system of isothiazolinones biocides

Aerogels of chemo-enzymatically oxidized, lyophilized fenugreek gum (EOLFG) were evaluated as ?delivery system? (DS) of the microbiocide mix 5-chloro-2-methyl-4-isothiazolin-3-one (CIT) and 2-methyl-4-isothiazolin-3-one (MIT). These biocides have a broad activity spectrum and a low MIC (minimal inhibitory concentration) in the ppm range. They are approved under the EU Biocidal Product Directive for various applications, including cosmetics, are classified as skin sensitizers, and are under increasing scrutiny to limit or eliminate their use. We demonstrate that CIT/MIT can be uptaken into EOLFG aerogel corks by immersion into aqueous solutions of microbiocides, followed by blotting and re-lyophilization to generate ?loaded? EOLFG aerogels. Incubation of ?loaded? corks in water brings about a slow and almost complete release of the absorbed actives having the same MIC of free biocides against selected bacterial pathogens. This new biomaterial could represent an innovative DS of microbiocides and other actives for a variety of industrial, food, cosmetic, and biomedical applications.

A retrospective look at anthranilic diamide insecticides: discovery and lead optimization to chlorantraniliprole and cyantraniliprole

Anthranilic diamides are an important commercial synthetic class of insecticides (IRAC Group 28) that bind to the ryanodine receptor with selective potency against insect versus mammalian forms of the receptor. The first commercialized diamide, chlorantraniliprole, has exceptional activity against lepidopteran pests. The second anthranilamide product, cyantraniliprole, has excellent cross-spectrum activity against a range of insect orders, including both lepidopteran and hemipteran pests. Here, a retrospective look is presented on the discovery of the class, along with chemistry highlights of the lead evolution to both products.

Thiazole and Isothiazole Ring?Containing Compounds in?Crop Protection

Organic compounds containing five-membered aromatic heterocyclic rings play an important role in life science. Among them thiazole and isothiazole heterocycles are present in many pharmaceutical drugs and crop protection compounds and have sparked over past years an enormous interest on these scaffolds. In agrochemicals these moieties are found in 11 commercial products as well as in two development compounds. A thiazole moiety is present in seven currently marketed agrochemicals, namely the insecticides thiamethoxam and clothianidin, the fungicides thiabendazole, thifluzamide, ethaboxam, and oxathiapiprolin, and the nematicide fluensulfone, as well as in the development compound dicloromezotiaz. One compound, the fungicide isotianil, contains an isothiazole ring and three compounds a benzothiazole ring, namely the fungicide benthiavalicarb and the herbicides methabenzthiazuron and mefenacet. A benzisothiazole ring is not yet present in any commercial product, however, is found in the former nematicide development compound benclothiaz. Interestingly thiazole and isothiazole heterocycles are much less frequently found in agrochemicals than pyridine and pyrazole despite their bioisosteric relationship, which may indicate that these heterocycles have still not been explored to their full scope in crop protection lead discovery and optimization. Detailed information on the discovery, synthesis, and the structure?activity relationships of thiazole- and isothiazole-containing agrochemicals is provided in this review.
