From March 1974 through July 1975, 76 (56%) of 133 persons who had worked at a pesticide plant that produced Kepone, chlorinated hydrocarbon insecticide, contracted previously unrecognized clinical illness characterized by nervousness, tremor, weight loss, opsoclonus, pleuritic and joint pain, oligospermia. Illness incidence rates for production workers (64%) were significantly higher than nonproduction personnel (16%). The mean blood Kepone level with was 2.53 ppm those without disease 0.60...
Blood lead levels were determined on a random sample of persons in all age groups living near lead-emitting smelter El Paso, Texas. A blood level greater than or equal to 40 mug per 100 ml, which was considered indicative undue absorption, found 53 cent the children one nine years old within 1.6 km and 18 those from 6.6 km; beyond that distance older lower. Children first with ml exposed 3.1 times as much dust there lower values (6447 vs 2067 ppm). There also airborne exposure (8 10 cubic...

Tetrachlorodibenzodioxin was identified as the apparent cause of an outbreak poisoning in humans, horses, and other animals. Exposure related to spraying contaminated waste oil on riding arenas for dust control. The contamination resulted from improper disposal a toxic industrial waste. pathologic effects chemical identification tetrachlorodibenzodioxin are described.
Abstract We describe epidemiological and laboratory investigation of a poisoning outbreak that involved three riding arenas killed fiftyseven horses, five colts, numerous other animals. The was traced to the spraying with salvage oil contaminated tetrachlorodibenzodioxin, trichlorophenol, polychlorinated biphenyls. contamination resulted from improper disposal toxic industrial waste.

Three branched-chain hydroxy acids not previously reported in other bacteria were found extracts from saponified whole cells of Pseudomonas maltophilia. On the basis evidence mass spectrometry, infrared spectroscopy, and gas chromatographic procedures, they identified as 2-hydroxy-9-methyldecanoic acid, 3-hydroxy-9-methyldecanoic 3-hydroxy-11-methyldodecanoic acid. These appeared to be tightly bound cellular components since extracted lyophilized with a chloroform-methanol (3:1) mixture.
Optimization of KDM6B (JMJD3) HTS hit 12 led to the identification 3-((furan-2-ylmethyl)amino)pyridine-4-carboxylic acid 34 and 3-(((3-methylthiophen-2-yl)methyl)amino)pyridine-4-carboxylic 39 that are inhibitors KDM4 (JMJD2) family histone lysine demethylases. Compounds possess activity, IC50 ≤ 100 nM, in biochemical (RFMS) assays with ≥ 50-fold selectivity against activity a mechanistic KDM4C cell imaging assay (IC50 = 6-8 μM). also potent KDM5C (JARID1C) (RFMS 100-125 nM).
Endoplasmic reticulum aminopeptidase 1 (ERAP1) is an intracellular enzyme that optimizes the peptide cargo of major histocompatibility class I (MHC-I) molecules and regulates adaptive immunity. It has unusual substrate selectivity for length sequence, resulting in poorly understood effects on cellular immunopeptidome. To understand selection by ERAP1, we solved 2 crystal structures with bound transition-state pseudopeptide analogs at 1.68 Å 1.72 Å. Both peptides have their N terminus active...
Kynurenine monooxygenase (KMO) blockade protects against multiple organ failure caused by acute pancreatitis (AP), but the link between KMO and systemic inflammation has eluded discovery until now. Here, we show that product 3-hydroxykynurenine primes innate immune signaling to exacerbate during experimental AP. We find a tissue-specific role for KMO, where mice lacking Kmo solely in hepatocytes have elevated plasma levels prime inflammatory gene transcription. 3-Hydroxykynurenine synergizes...

Abstract Kynurenine-3-monooxygenase (KMO) is a key FAD-dependent enzyme of tryptophan metabolism. In animal models, KMO inhibition has shown benefit in neurodegenerative diseases such as Huntington’s and Alzheimer’s. Most recently it been identified target for acute pancreatitis multiple organ dysfunction syndrome (AP-MODS); devastating inflammatory condition with mortality rate excess 20%. Here we report dissect the molecular mechanism action three classes inhibitors differentiated binding...
ER aminopeptidase 1 (ERAP1) is an intracellular enzyme that generates antigenic peptides and emerging target for cancer immunotherapy the control of autoimmunity. ERAP1 inhibitors described previously active site are limited in selectivity, minimizing their clinical potential. To address this, we targeted regulatory using a high-throughput screen discovered small molecule hit highly selective ERAP1....

Kynurenine 3-monooxygenase (KMO) is a therapeutically important target on the eukaryotic tryptophan catabolic pathway, where it converts L-kynurenine (Kyn) to 3-hydroxykynurenine (3-HK). We have cloned and expressed human form of this membrane protein as full-length GST-fusion in recombinant baculovirus expression system. An enriched preparation was used for directed screen approximately 78,000 compounds using RapidFire mass spectrometry (RF-MS) assay. The platform provides an automated...
