Isolation, purification, and characterization of lectins from medicinal plant Combretum glutinosum seeds endowed with analgesic and antiulcer properties. Biochimie 2024:S0300-9084(24)00180-9. [PMID: 39102999 DOI: 10.1016/j.biochi.2024.08.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2024] [Revised: 06/19/2024] [Accepted: 08/02/2024] [Indexed: 08/07/2024]
Abstract
In the pursuit of safer and more effective treatments, there is a growing interest in plant-derived compounds, particularly lectins, because of their diverse pharmacological properties. This study focused on isolating, purifying, and characterizing lectin from Combretum glutinosum seeds (CGSLs) to assess its potential as an analgesic and antiulcer agent. CGSL extraction involved defatting and buffer extraction, followed by purification using ammonium sulfate fractionation and fetuin-agarose affinity column chromatography. The isolectins (iso-CGSLs), each consisting of 60 kDa and 57 kDa heterodimeric subunits, displayed glycoprotein properties with a 40 % neutral sugar content. They exhibited peak activity at 55 °C and remained stable for up to the fifth day at room temperature. The activity exhibited a pH dependence, peaking between 7.5 and 10.5, and all seemingly operated independently of metal ions. CGSL, at optimal doses ranging from 6 to 12 mg/kg, had significant analgesic effects on acetic acid-induced writhing and hot plate tests in mice. Evaluation using 0.7 % acetic acid resulted in notable pain reduction across all doses (P < 0.05). The analgesic effect of lectin was partially reversed by naloxone (a morphine antagonist), indicating partial involvement of the opioid receptor system. Furthermore, CGSL exhibited antiulcer effects in ethanol-induced gastric ulcer models in rats, highlighting its therapeutic potential as a natural alternative for analgesic and antiulcer treatments.

[PMID: 31978534 DOI: 10.1016/j.pep.2020.105574] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Revised: 01/20/2020] [Accepted: 01/20/2020] [Indexed: 10/25/2022]
Abstract
BACKGROUND Lectins are known to possess interesting biological properties such as anti microbial, nematicidal, anti tumor and anti viral activities. Lantana camara from verbenaceae family is a medicinal plant known for possessing anti oxidant and anticancer activities. Since anticancer activity is reported in plant lectins, leaves of Lantana camara was used to check the presence of lectin. METHODS AND RESULTS Here we report the purification, characterization and biological properties of a lectin from Lantana camara (LCL) leaves. LCL was purified by ion exchange chromatography on CM-cellulose column followed by affinity chromatography on mucin coupled Sepharose 4B column and gel filtration chromatography on Superdex G75 column. LCL is a glycoprotein with 10% of the carbohydrate and is blood group non specific. SDS-PAGE analysis of affinity purified LCL showed two proteins with apparent molecular weight of 14.49 kDa and 17.4 kDa which were subsequently separated by Gel filtration chromatography on Superdex G75 column. Hapten inhibition studies of LCL revealed its highest affinity for Chitin, Milibiose, α-D-Methyl galactopyranoside and glycoproteins like mucin, asialomucin. LCL showed strong binding to human colon adenocarcinoma HT29 cells with MFI of 242 which was effectively blocked by 68.1 and 62.5% by both mucin and milibiose. LCL showed dose and time dependent growth inhibitory effects on HT29 cells with IC50 of 3.75 μg/ml at 48 h. LCL has potent antibacterial and anti fungal activity. CONCLUSION LCL can be explored for its clinical potential.

Abstract
The development of an orientation immobilization technique via affinity between polyhistidine tags and metal ions aims at maintaining biocatalytic activity of the enzymes. In this work, to tackle the issue of the immobilization of adenylate cyclase (AC), a simple and effective approach of synthesizing iminodiacetic acid (IDA)-Ni2+ particles was applied for simultaneously purifying and immobilizing his-tagged AC. We chose agarose particles as carriers, and then decorated them with IDA, leading to the formation of a coordination combination of Ni2+. The porous carriers with a large pore size of 50 nm and a specific surface area of 45.8 m2/g exhibited favorable enzymatic activity and loading capacity. The optimal pH of the immobilized enzyme increased from 8.0 to 9.0 and the optimal temperature increased from 30 °C to 35 °C, compared to the free AC. Moreover, the immobilized AC retained a residual activity of approximately 80% after storing it at 25 °C for 48 h, whereas only 40% of the activity was left in the free AC at the same conditions. Maximum yield of cyclic adenosine-3', 5'- monophosphate (cAMP) reached up to the summit of the reaction. The immobilized AC by affinity adsorption will provide a promising route for the industrial production of cAMP.

Abstract
Lectins (hemagglutinins) are defined as sugar-binding proteins or glycoproteins with various biological activities. A 60 kDa dimeric hemagglutinin with a blocked N-terminus was isolated in large yield (190 mg/60 g) from the common edible bean Phaseolus vulgaris cv. Hokkaido large pinto bean. Its hemagglutinating, antifungal, and antitumor activities as well as the effects of carbohydrate and metal ions on its hemagglutinating activity were examined. It inhibited the proliferation of nasopharyngeal carcinoma (CNE2), human breast cancer (MCF7), and hepatoma (HepG2) cells. The IC50 values toward HepG2, MCF7, and CNE2 cells after treatment for 48 h were 8.1, 6.07, and 7.49 μM, respectively, which were relatively low among lectins of different P. vulgaris cultivars. From the pinto beans, a 10888 Da antifungal peptide with similarity to plant defensins as revealed by mass spectroscopic analysis was also isolated with a yield of 3.2 mg of proteins from 60 g of beans. The large defensin was capable of inhibiting mycelial growth in Mycosphaerella arachidicola, Setosphaeria turcica, Bipolaris maydis, and Fusarium oxysporum but not in Valsa mali.
