Physicochemical Characterizations and Antioxidant Property of Copaiba Oil Loaded into SNEDDS Systems
A method of preparing the protein coats or ghosts of phage T2 is described along with proof that the lytic action is a property of the ghost. An assay based on the lytic action toward host cells has been developed which permits a rapid evaluation of the number of ghosts with a reliability of +/-15 per cent. The antigenic and certain physicochemical properties of the ghost have been determined.
Chitosan-pectin, chitosan-alginate and chitosan-pectin-alginate scaffolds were prepared by freeze-drying technique. The physicochemical characteristics of the scaffolds were characterized by FTIR and SEM. The biological activities like antibacterial assessment, swelling behavior, biodegradation and cytotoxicity study of the prepared scaffolds were evaluated. The results show high swelling prope...
The ethanol crude extract of stem bark of Holoptelea integrifolia Planch. traditionally used in Indian system of medicine was screened for its antioxidant activity using α-tocopherol as standard antioxidant. The free radical scavenging potential of the extract was evaluated by two different antioxidant methods; ferric thiocyanate and thiobarbituric acid method. The ethanol extract was found to ...
The Mediator complex-associated cyclin-dependent kinase CDK8 has been implicated in human disease, particularly in colorectal cancer where it has been reported as a putative oncogene. Here we report the discovery of 109 (CCT251921), a potent, selective, and orally bioavailable inhibitor of CDK8 with equipotent affinity for CDK19. We describe a structure-based design approach leading to the disc...
Biokinetic studies of zinc oxide (ZnO) nanoparticles involve systematic and quantitative analyses of absorption, distribution, metabolism, and excretion in plasma and tissues of whole animals after exposure. A full understanding of the biokinetics provides basic information about nanoparticle entry into systemic circulation, target organs of accumulation and toxicity, and elimination time, whic...
UNLABELLED BACKGROUND In this work, we analyzed and compared the distribution profiles of a wide variety of molecular properties for three compound classes: drug-like compounds in MDL Drug Data Report (MDDR), non-drug-like compounds in Available Chemical Directory (ACD), and natural compounds in Traditional Chinese Medicine Compound Database (TCMCD). RESULTS The comparison of the property ...
This paper presents a novel feature vector based on physicochemical property of amino acids for prediction protein structural classes. The proposed method is divided into three different stages. First, a discrete time series representation to protein sequences using physicochemical scale is provided. Later on, a wavelet-based time-series technique is proposed for extracting features from mapped...
A series of N(2),N(4)-disubstituted quinazoline-2,4-diamines has been synthesized and tested against Leishmania donovani and L. amazonensis intracellular amastigotes. A structure-activity and structure-property relationship study was conducted in part using the Topliss operational scheme to identify new lead compounds. This study led to the identification of quinazolines with EC50 values in the...
