Plant protease inhibitors (PPIs) are one of the important components of a plant's defense machinery. PPIs are active against the insects and microbes which invade the plant. Cassia species possess anti-insecticidal and antimicrobial properties and this study was aimed at investigating the

A novel trypsin inhibitor was extracted from the seeds of Cassia fistula by a process successively involving soaking seeds in water, extraction of the seeds in methanol, and extraction of the cell wall material at high ionic strength. The protease inhibitor (PI) was subsequently purified by

Infections caused by Candida tropicalis have increased significantly worldwide in parallel with resistance to antifungal drugs. To overcome resistance novel drugs have to be discovered. The objective of this work was to purify and characterize a cysteine protease inhibitor from the seeds of the

BACKGROUND Proteases play an important role in virulence of many human, plant and insect pathogens. The proteinaceous protease inhibitors of plant origin have been reported widely from many plant species. The inhibitors may potentially be used for multiple therapeutic applications in viral,

Cassia leiandra is an Amazonian plant species that is used popularly for the treatment of mycoses. Recently, a protease inhibitor, named ClTI, with insecticidal activity against Aedes aegypti, was purified from the mature seeds of C. leiandra. In this work, we show that ClTI has antifungal activity

A thermotolerant protein with trypsin inhibitory activity designated as CaTI was purified to homogeneity from seeds of Cassia absus. Gel filtration chromatography and SDS-PAGE analysis showed the apparent molecular mass of ~20 kDa. Partial internal sequences indicate that CaTI belongs to

BACKGROUND Human Immunodeficiency Virus (HIV) strains resistant to licensed anti-retroviral drugs (ARVs) continue to emerge. On the African continent, uneven access to ARVs combined with occurrence of side-effects after prolonged ARV therapy have led to searches for traditional medicines as

Natural products are used as alternative drugs in traditional medicine to treat infection and inflammation and relieve pain. Heartwood of Cassia garettiana Craib has been investigated as an ingredient in Thai traditional medicine for anti-HIV protease, but there is no report on its

Viper bites cause high morbidity and mortality especially in tropical and subtropical regions, affecting a large number of the rural population in these areas. Even though anti-venoms are available, in most cases they fail to tackle viper venom-induced local manifestations that persist even after

Pieris rapae, a serious Lepidoptera pest of cultivated crucifers, utilizes midgut enzymes to digest food and detoxify secondary metabolites from host plants. A recombinant trypsin inhibitor (COTI) from nonhost plant, Cassia obtusifolia, significantly decreased activities of trypsin-like proteases in

Adaptation to plant allelochemicals is a crucial aspect of herbivore chemical ecology. To understand an insect ecology, we studied an effect of nonhost Cassia tora seed-based diet (Ct) on growth, development, and molecular responses in Helicoverpa armigera. We employed a comparative approach to

Development of anti-severe acute respiratory syndrome associated coronavirus (SARS-CoV) agents is pivotal to prevent the reemergence of the life-threatening disease, SARS. In this study, more than 200 extracts from Chinese medicinal herbs were evaluated for anti-SARS-CoV activities using a

Although digestive resistance of Kunitz protease inhibitors has been reported extensively, the molecular mechanism is not well established. In the present study, the first X-ray structure of Cassia obtusifolia trypsin inhibitor (COTI), a member of Kunitz protease inhibitors, was solved at a

A trypsin inhibitor gene (CoTI1) from Cassia obtusifolia was isolated and the deduced amino acid sequence was attributed to the Kunitz-type trypsin inhibitor. The recombined CoTI1, expressed in E. coli, exhibited strong inhibitory effect on bovine trypsin and trypsin-like proteases from Helicoverpa

The popular beverage ingredients Cassia obtusifolia and Cassia tora were found to have considerable amounts of water-soluble polysaccharides (WSPs) (58.5 and 55.9/100g of dried extract). The composition, characteristics, and in-vitro physiological effects of these polysaccharides and their possible
