A modified gas liquid chromatography method has been developed to analyse the concentrations of indole and 3-methylindole in samples of plasma and rumen fluid from four cows with fog fever together with four control animals and from two cattle given L-tryptophan orally. Satisfactory recoveries of
BACKGROUND
Previous studies have demonstrated that centrally administered natriuretic peptides and pituitary adenylate cyclase-activating polypeptide-38 (PACAP-38) have hyperthermic properties. Isatin (indole-2, 3-dione) is an endogenous indole that has previously been found to inhibit hyperthermic
The effects of an endogenous indole, isatin (indole-2, 3-dione), on the hyperthermia induced by atrial natriuretic peptide (ANP-28), brain natriuretic peptide (BNP-32), and C-type natriuretic peptide (CNP-22) were investigated in rats. Intracerebroventricular administration of each peptide in a dose
Mosquitoes are highly dependent on their olfactory system for, e.g. host location and identification of nectar-feeding and oviposition sites. Odours are detected by olfactory receptor neurons (ORNs) housed in hair-shaped structures, sensilla, on the antennae and maxillary palps. In order to unravel
Abstract
A series of
indole-based spirothiazolidinones have been designed, synthesized and evaluated, in vitro, for their antitubercular, antiviral, antibacterial, and antifungal activities. The structures of the new compounds were established by IR,
1H NMR,
Ethnopharmacological relevance: Neolamarckia cadamba has been used traditionally to treat inflammation, fever, and pruritus in the Dai ethnopharmacy in Yunnan province, P.R. China. However, according to literature survey, the action basis
Aedes aegypti, the principal vector of yellow fever and dengue fever, is responsible for more than 30,000 deaths annually. Compounds such as carbon dioxide, amino acids, fatty acids and other volatile organic compounds (VOCs) have been widely studied for their role in attracting Ae. aegypti to
A new indole alkaloid, named donasine, has been isolated from the rhizomes of Arundo donax L. Its structure was determined by X-ray crystallographic analysis and spectral methods. The primary pharmacological test showed that the compound has an action of reducing fever.
BACKGROUND
5-(2-aminopropyl)indole (5-IT) is a new psychoactive substance (NPS; "legal high" or "research chemical") structurally related to indoleamines and substituted phenethylamines and implicated in several fatalities. We describe the clinical characteristics and results of laboratory
Dengue virus (DENV) is transmitted to humans by Aedes mosquitoes and is a public health issue worldwide. No antiviral drugs specific for treating dengue infection are currently available. To identify novel DENV inhibitors, we analyzed a library of 95 compounds and 120 extracts derived from crude
Reported herein is the design, synthesis, and pharmacologic evaluation of a class of TRPV1 antagonists constructed on 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole as A-region and triazole as B-region. The SAR analysis indicated that 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole analogues displayed
Selective inhibitors of the replication of the classical swine fever virus (CSFV) may have the potential to control the spread of the infection in an epidemic situation. We here report that 5-[(4-bromophenyl)methyl]-2-phenyl-5H-imidazo[4,5-c]pyridine (BPIP) is a highly potent inhibitor of the in
BACKGROUND
Several species of Aspidosperma (Apocynaceae) are used as treatments for human diseases in the tropics. Aspidosperma olivaceum, which is used to treat fevers in some regions of Brazil, contains the monoterpenoid indole alkaloids (MIAs) aspidoscarpine, uleine, apparicine, and
Infusions of Aspidosperma nitidum (Apocynaceae) wood bark are used to treat fever and malaria in the Amazon Region. Several species of this family are known to possess indole alkaloids and other classes of secondary metabolites, whereas terpenoids, an inositol and the indole alkaloids harmane-3 acid
Close structural analogues of 5-carboxamidotryptamine (5-CT) based on the newly discovered indole-imidazole scaffold were synthesized and evaluated to search for a 5-HT7 receptor agonist of higher selectivity. In vitro drug-likeness studies and in vivo pharmacological
