1. Lithocholic acid-24-l% was administered to rats and labeled hyodeoxycholic acid was isolated from feces and from bile collected after 3 days of intact enterohepatic circulation. Labeled 3a-hydroxy-6-keto-5P-cholanoic acid was isolated from feces. No labeled hyodeoxycholic acid was formed when lithocholic acid-24-l% was administered to bile fistula rats. One of the major metabolites in these ...
Keratitis treatment has become more complicated due to the emergence of bacterial or fungal pathogens with enhanced antibiotic resistance. The pharmaceutical applications of N-heterocyclic carbene complexes have received remarkable attention due to their antimicrobial properties. In this paper, the new precursor, 3,3'-(p-phenylenedimethylene) bis{1-(2- methyl-allyl)imidazolium} bromide (1a) and...
Despite extraordinary diversity in the rodent order, studies of motor cortex have been limited to only 2 species, rats and mice. Here, we examine the topographic organization of motor cortex in the Eastern gray squirrel (Sciurus carolinensis) and cortical connections of motor cortex in the California ground squirrel (Spermophilus beecheyi). We distinguish a primary motor area, M1, based on intr...
An improved and scalable synthesis of the unsubstituted 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene framework facilitates access to the previously unreported parent dipyrrin HCl salt, as well as 4,4-dichloro-4-bora-3a,4a-diaza-s-indacene.
The poliovirus RNA replication complex comprises multiple viral and possibly cellular proteins assembled on the cytoplasmic surface of rearranged intracellular membranes. Viral proteins 3A and 3AB perform several functions during the poliovirus replicative cycle, including significant roles in rearranging membranes, anchoring the viral polymerase to these membranes, inhibiting host protein secr...
Nutlin-3a is an MDM2 inhibitor that is under investigation in preclinical models for a variety of pediatric malignancies, including retinoblastoma, rhabdomyosarcoma, neuroblastoma, and leukemia. We used physiologically based pharmacokinetic (PBPK) modeling to characterize the disposition of nutlin-3a in the mouse. Plasma protein binding and blood partitioning were assessed by in vitro studies. ...
Address for correspondence Mr. Mohammad Asif, Department of Pharmacy, GRD (P.G) Institute of Management and Technology, 214-Rajpur Road, Dehradun (U.K), 248009, India. Phone No: +91-9897088910 E-mail: [email protected] ABSTRACT Purpose: In the present study, antitubercular activities and in silico physicochemical toxicities and bioactivity profile of some 3-chloro-6-arylpyridazines (3a-d) and ...
A new chemical component, cis-Z,Z'-3a.7a',7a.3a'-dihydroxyligustilide, was isolated from Angelica sinensis and its structure elucidated from its NMR and MS spectra and confirmed by X-ray single crystal diffraction analysis. We also explored the antioxidative properties of cis-Z,Z'-3a.7a',7a.3a'-dihydroxyligustilide on human umbilical vein endothelial cells (HUVECs) against injuries induced by h...
Axonal guidance is key to the formation of neuronal circuitry. Semaphorin 3A (Sema 3A; previously known as semaphorin III, semaphorin D, and collapsin-1), a secreted subtype of the semaphorin family, is an important axonal guidance molecule in vitro and in vivo. The molecular mechanisms of the repellent activity of semaphorins are, however, poorly understood. We have now found that the secreted...
