OBJECTIVE The predicted amino acid sequence of locus plu4437-plu4436 in the genome of Photorhabdus luminescens TT01 (referred to as pirA2B2) has a consistency of 50% and 45% with locus plu4093-plu4092 (referred to as pirA1B1) , respectively. PirA1B1 has been confirmed with oral insecticidal activity against Plutella xylostella and mosquito. The purpose of(More)
A new class of highly potent NS5A inhibitors with an unsymmetric benzimidazole-difluorofluorene-imidazole core and distal [2.2.1]azabicyclic ring system was discovered. Optimization of antiviral potency and pharmacokinetics led to the identification of 39 (ledipasvir, GS-5885). Compound 39 (GT1a replicon EC50 = 31 pM) has an extended plasma half-life of(More)
Lactate dehydrogenase (LDH) is an essential metabolic enzyme that catalyzes the interconversion of pyruvate and lactate using NADH/NAD(+) as a co-substrate. Many cancer cells exhibit a glycolytic phenotype known as the Warburg effect, in which elevated LDH levels enhance the conversion of glucose to lactate, making LDH an attractive therapeutic target for(More)
Starting from the oxindole 2a identified through a high-throughput screening campaign, a series of Na(V)1.7 blockers were developed. Following the elimination of undesirable structural features, preliminary optimization of the oxindole C-3 and N-1 substituents afforded the simplified analogue 9b, which demonstrated a 10-fold increase in target potency(More)
Inhibition of intestinal brush border DMT1 offers a novel therapeutic approach to the prevention and treatment of disorders of iron overload. Several series of diaryl and tricyclic benzylisothiourea compounds as novel and potent DMT1 inhibitors were discovered from the original hit compound 1. These compounds demonstrated in vitro potency against DMT1,(More)
BACKGROUND Therapeutic antibody development is one of the fastest growing areas of the pharmaceutical industry. Generating high-quality monoclonal antibodies against a given therapeutic target is crucial for successful drug development. However, due to immune tolerance, making it difficult to generate antibodies using conventional approaches. (More)
There is accumulating evidence that many invertebrates including insects can acquire enhanced immune protection against subsequently pathogens infection through immune priming. However, whether the toxin protein from pathogenic bacteria can induce such priming response remains unclear. Here we cloned, expressed and purified the toxin Photorhabdus(More)
Geometry property would affect the hydrodynamics of membrane bioreactor (MBR), which was directly related to membrane fouling rate. The simulation of a bench-scale MBR by computational fluid dynamics (CFD) showed that the shear stress on membrane surface could be elevated by 74% if the membrane was sandwiched between two baffles (baffled MBR), compared with(More)
