In this study, we have analyzed the structural and functional changes in the nature of Allium sativum Protease Inhibitor (ASPI) on undergoing various denaturation with variable range of pH, temperature and urea (at pH 8.2). ASPI being anti-tryptic in nature has native molecular mass of ∼15kDa. The

OBJECTIVE The aim of this study was to elucidate the impact of first-pass intestinal metabolism to therapeutic efficacy of antiretrovirals and to ascertain interaction mechanisms between garlic supplements (aged garlic extract) and HIV-protease inhibitors. METHODS In vitro permeability through rat

The purpose of this study was to evaluate in vitro interactions of commercially obtained pure herbal constituents with p-glycoprotein P-gp and cytochrome P-450 3A4 (CYP3A4) activities, which can further modulate the transcellular transport and metabolism kinetics of orally administered drugs. Caco-2

The outbreak of novel coronavirus disease (COVID-19) caused by SARS-CoV-2 poses a serious threat to human health and world economic activity. There is no specific drug for the treatment of COVID-19 patients at this moment. Traditionally, people have been using spices like ginger, fenugreek and

BACKGROUND Garlic-derived organosulfur compounds such as diallyl sulfide (DAS), diallyl disulfide (DADS), and diallyl trisulfide (DATS) provide significant protection against carcinogenesis. METHODS Dose-dependent cytotoxic effects of the garlic compounds (DAS, DADS, and DATS) were tested in human

OBJECTIVE This study was aimed to purify and characterize the Protease inhibitor (PI) from a plant Allium sativum (garlic) with strong medicinal properties and to explore its phytodrug potentials. METHODS Allium sativum Protease Inhibitor (ASPI) was purified using ammonium sulphate fractionation and

Garlic phytochemicals and garlic supplements influence the pharmacokinetic and pharmacodynamic behavior of concomitantly ingested drugs. In this paper we have summarized the mechanisms responsible for first-pass intestinal pharmacokinetic interactions by investigating the intestinal permeability of

The 26S proteasome (multicatalytic protease complex, MPC) was purified from fresh garlic cloves (Allium sativum) to near homogeneity by ion exchange chromatography on DEAE-sephacel, gel filtration on Sepharose-4B, and glycerol density gradient centrifugation. Two alpha-type (20S proteasome

A protein designated alliumin, with a molecular mass of 13 kDa and an N-terminal sequence similar to a partial sequence of glucanase, and demonstrating antifungal activity against Mycosphaerella arachidicola, but not against Fusarium oxysporum, was isolated from multiple-cloved garlic (Allium

Cysteine proteinase inhibitors play an essential role in maintaining the proper functioning of all living cells by virtue of its thiol protease regulatory properties. Chemical denaturation of a new variant of cystatin super family has been studied by various biophysical techniques in order to

Allium sativum leaf agglutinin (ASAL) binds to several proteins in the midgut of Helicoverpa armigera and causes toxicity. Most of these were glycosylated. Six ASAL-binding proteins were selected for identification. PMF and MS/MS data showed their similarity with midgut aminopeptidase APN2,

Over expression of lectin genes in E. coli often gives inclusion bodies that are solubilised to characterize lectins. We made N-terminal fusion of the Allium sativum leaf agglutinin (ASAL) with SUMO (small ubiquitin related modifier) peptide. The SUMO peptide allowed expression of the recombinant

OBJECTIVE To develop and optimize cDNA representational difference analysis (cDNA RDA) method and to identify and clone garlic up-regulated genes in human gastric cancer (HGC) cells. METHODS We performed cDNA RDA method by using abundant double-stranded cDNA messages provided by two self-constructed

Eighteen fungal species were isolated from rhizospheric soil and rhizoplane samples of three plant crops in southern Iraq. The fungal isolates were examined for the activities of four enzymes (amylase, cellulase, phenoloxidase, and protease), as well as their growth, against crude garlic extract

Oxyfluorfen (2-chloro-1-(3-ethoxy-4-nitrophenoxy)-4-(trifluoromethyl)benzene) is a nitrophenyl ether herbicide. Phytocystatins are crucial plant proteins which regulate various physiological processes and are also responsible for maintaining protease-antiprotease balance within plants. Thus, the
