Abstract
Recombinant human arginase I (rhArg I) have emerged as a potential candidate for the treatment of varied pathophysiological conditions ranging from arginine-auxotrophic cancer, inflammatory conditions and microbial infection. However, rhArg I have a low circulatory half-life, leading to poor pharmacokinetic and pharmacodynamic properties, which necessitating the rapid development of modifications to circumvent these limitations. To address this, polyethylene glycol (PEG)ylated-rhArg I variants are being developed by pharmaceutical companies. However, because of the limitations associated with the clinical use of PEGylated proteins, there is a dire need in the art to develop rhArg I variant(s) which is safe (devoid of limitations of PEGylated counterpart) and possess increased circulatory half-life. In this study, we described the generation and characterization of a fused human arginase I variant (FHA-3) having improved circulatory half-life. FHA-3 protein was engineered by fusing rhArg I with a half-life extension partner (domain of human serum albumin) via a peptide linker and was produced using P. pastoris expression system. This purified biopharmaceutical (FHA-3) exhibits (i) increased arginine-hydrolyzing activity in buffer, (ii) cofactor - independency, (iii) increased circulatory half-life (t1/2) and (iv) potent anti-cancer activity against human cancer cell lines under in vitro and in vivo conditions.
