Srivastava G, Mittal R, Srivastava N, Ganjewala D. Exploring the potential of two Pseudomonas species to produce vincristine from vinblastine via biotransformation. Sci Rep 2024; 14:19652. [PMID: 39179785 PMCID: PMC11344160 DOI: 10.1038/s41598-024-70571-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Accepted: 08/19/2024] [Indexed: 08/26/2024] Open
Abstract
A biotransformation pair consisting of vinblastine: vincristine present in the Catharanthus roseus plant is of immense pharmacological significance. In this study, we successfully transformed vinblastine into vincristine outside the plant using Pseudomonas aeruginosa 8485 and Pseudomonas fluorescens 2421 and evaluated the antiangiogenic potential of thus produced vincristine through the CAM assay. The toxicity assay showed that both Pseudomonas spp. can tolerate varying concentrations (25-100 µl of 1 mg/ml) of vinblastine. The biotransformation was performed in a liquid nutrient broth medium containing vinblastine (25-100 µl), and Pseudomonas spp. inoculums (50-150 µl) by incubating at 30 °C and 37 °C, respectively for 8 days. The process was optimized for substrate and culture concentrations, pH, temperature, and rotation speed (rpm) for the highest conversion. Analysis using LC-MS/MS confirmed the presence of vincristine as a product of the vinblastine biotransformation by two Pseudomonas spp. P. fluorescens 2421 showed a faster conversion rate with 95% of vinblastine transformed within 24 h than P. aeruginosa 8485, which demonstrated a conversion rate of 92% on the 8th day. From LC-MS/MS analysis, the optimal conditions for the reaction were determined as vinblastine (25 µl), microbial inoculums (150 µl or 200 × 106 and 210 × 106 CFU/ml), pH 7.4, rotation speed of 180 rpm, and temperatures of 30 °C and 37 °C with incubation time of 8 days. The vincristine produced exhibited potent antiangiogenic activity in the CAM assay reducing the thickness and branching of blood vessels in a dose-dependent manner. The study concludes that both Pseudomonas spp. showed promise for vincristine production from vinblastine, without compromising its antiangiogenic properties.

Abstract
In the present study, an effective method of preparative high-performance liquid chromatography (Prep-HPLC) was established to purify two taxanes in Taxus cuspidata. During the experimental operation, the effects of flow rate, injection volume, and column temperature on the purity of 10-deacetyltaxol (10-DAT) and paclitaxel (PTX) were investigated, and the optimized conditions were as follows: flow rate of 10 mL/min, injection volume of 0.5 mL, and column temperature of 30 °C. Under these conditions, the purity of 10-DAT and PTX reached 95.33% and 99.15%, respectively. The purified products were characterized by scanning electron microscopy (SEM), high-performance liquid chromatography (HPLC), and electrospray ionization-high resolution mass spectrometry (ESI-HRMS). The results demonstrated that preparative HPLC can effectively purify 10-DAT and PTX from Taxus cuspidata with a purity of >95%, which was suitable for the large-scale preparation of 10-DAT and PTX.

Abstract
Natural products are structurally and biologically interesting metabolites, but they have been isolated in minute amounts. The syntheses of such natural products help in obtaining them in bulk amounts. The recognition of microbial biotransformation as important manufacturing tool has increased in chemical and pharmaceutical industries. In recent years, microbial transformation is increasing significantly from limited interest into highly active area in green chemistry including preparation of pharmaceutical products. This is the first review published on the usage of microbial biocatalysts for some natural product classes and natural product drugs.

Taxane's substituents at C3' affect its regioselective metabolism: different in vitro metabolism of cephalomannine and paclitaxel. Drug Metab Dispos 2007; 36:418-26. [PMID: 18039807 DOI: 10.1124/dmd.107.018242] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022] Open
Abstract
To investigate how taxane's substituents at C3' affect its metabolism, we compared the metabolism of cephalomannine and paclitaxel, a pair of analogs that differ slightly at the C3' position. After cephalomannine was incubated with human liver microsomes in an NADPH-generating system, two monohydroxylated metabolites (M1 and M2) were detected by liquid chromatography/tandem mass spectrometry. C4'' (M1) and C6alpha (M2) were proposed as the possible hydroxylation sites, and the structure of M1 was confirmed by (1)H NMR. Chemical inhibition studies and assays with recombinant human cytochromes P450 (P450s) indicated that 4''-hydroxycephalomannine was generated predominantly by CYP3A4 and 6alpha-hydroxycephalomannine by CYP2C8. The overall biotransformation rate between paclitaxel and cephalomannine differed slightly (184 vs. 145 pmol/min/mg), but the average ratio of metabolites hydroxylated at the C13 side chain to C6alpha for paclitaxel and cephalomannine varied significantly (15:85 vs. 64:36) in five human liver samples. Compared with paclitaxel, the major hydroxylation site transferred from C6alpha to C4'', and the main metabolizing P450 changed from CYP2C8 to CYP3A4 for cephalomannine. In the incubation system with rat or minipig liver microsomes, only 4''-hydroxycephalomannine was detected, and its formation was inhibited by CYP3A inhibitors. Molecular docking by AutoDock suggested that cephalomannine adopted an orientation in favor of 4''-hydroxylation, whereas paclitaxel adopted an orientation favoring 3'-p-hydroxylation. Kinetic studies showed that CYP3A4 catalyzed cephalomannine more efficiently than paclitaxel due to an increased V(m). Our results demonstrate that relatively minor modification of taxane at C3' has major consequence on the metabolism.

Abstract
Considerable progress has been made in manipulating oxidative biotransformations using oxygenases. Substrate acceptance, catalytic activity, regioselectivity and stereoselectivity have been improved significantly by substrate engineering, enzyme engineering or biocatalyst screening. Preparative biotransformations have been carried out to synthesize useful pharmaceutical intermediates or chiral synthons on the gram to several-hundred-gram scale, by use of whole cells of wild type or recombinant strains. The synthetic application of oxygenases in vitro has been shown to be possible by enzymatic or electrochemical regeneration of NADH or NADPH.
