Abstract
L-asparaginase is used in chemotherapy for acute lymphoblastic leukemia and other
cancers. L-asparaginase derived from bacterial source triggers immune responses.
The current study investigates Solanum nigrum as a novel and
latent source of L-asparaginase to minimize immunological reactions. The
antitumor activity of SN methanol extract was determined using the potato disc
assay. InterPro Chimera and InterPro were used to predict the amino acid
sequence of L-asparaginase and its anticancer activity. Purification of the
enzyme was carried out to homogeneity of 1.51-fold with a recovery of 61.99%. At
optimal conditions of 36.5°C, pH 8.6, and 8.5 g/mL substrate, fruit (crude
extract) revealed an L-asparaginase titer of 48.23 U/mL. The molecular weight of
the enzyme was calculated to be 32 ± 5 kDa using SDS PAGE. The fruit’s total
flavonoids and phenolic contents are 0.42 ± .030 g/mL and 94 ± 1.9 mg CAE,
respectively. Anti-tumorigenic efficacy was determined to be 66% against
Agrobacterium tumefaciens. Additionally, the extract
possesses potent antifungal and antibacterial properties. Molecular docking
provided the structural motifs and underlying interactions between
L-asparaginase, N-acetylglucosamine, murine, and chitin. SN contains high levels
of the enzyme L-asparaginase and phytochemicals, making it a potential source of
anticancer drugs.
