Abstract
Imiquimod (1-isobutyl-1H-imidazo[4,5-c]quinolin-4-amine) is efficacious in topical therapy for certain types of skin cancers. Structurally similar EAPB0203 (N-methyl-1-(2-phenethyl)imidazo[1,2-a]quinoxalin-4-amine) has been shown higher in vitro potency than imiquimod. Besides, triazole, oxadiazole, and thiadiazole rings are privileged building blocks in drug design. A series of [1,2,4]triazolo[4,3-a]quinoxaline-1,3,4-oxadiazole and [1,2,4]triazolo[4,3-a]quinoxaline-1,3,4-thiadiazole derivatives were therefore synthesized by incorporation of these rings into the structure of EAPB0203 and assessed their antiproliferative effects against various cancer cell lines. The 1,3,4-oxadiazole derivatives demonstrated the superior effectiveness compared to imiquimod and EAPB0203. Our findings highlight the excellent potential of [1,2,4]triazolo[4,3-a]quinoxaline-1,3,4-oxadiazole derivatives as anticancer agents.

Abstract
Drug metabolism is one of the most important pharmacokinetic processes and plays an important role during the stage of drug development. The metabolite profile investigation is important as the metabolites generated could be beneficial for therapy or leading to serious toxicity. This systematic review aims to summarize the research articles relating to the metabolite profile investigation of conventional drugs and herb-derived compounds for cancer chemotherapy, to examine factors influencing metabolite profiling of these drugs/compounds, and to determine the relationship between therapeutic efficacy and toxicity of their metabolites. The literature search was performed through PubMed and ScienceDirect databases up to January 2019. Out of 830 published articles, 78 articles were included in the analysis based on pre-defined inclusion and exclusion criteria. Both phase I and II enzymes metabolize the anticancer agents/herb-derived compounds . The major phase I reactions include oxidation/hydroxylation and hydrolysis, while the major phase II reactions are glucuronidation, methylation, and sulfation. Four main factors were found to influence metabolite formation, including species, gender, and route and dose of drug administration. Some metabolites were identified as active or toxic metabolites. This information is critical for cancer chemotherapy and anticancer drug development.

Liquid chromatography-electrospray ionization-tandem mass spectrometry method for quantitative estimation of new imiqualine leads with potent anticancer activities in rat and mouse plasma. Application to a pharmacokinetic study in mice. J Pharm Biomed Anal 2018; 148:369-379. [PMID: 29111492 DOI: 10.1016/j.jpba.2017.10.025] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2017] [Revised: 09/19/2017] [Accepted: 10/22/2017] [Indexed: 11/22/2022]
Abstract
Imidazoquinoxaline derivatives (imiqualines) are a new series of anticancer compounds. Two lead compounds (EAPB0203 and EAPB0503) with remarkable in vitro and in vivo activity on melanoma and T-cell lymphomas have been previously identified. The modulation of the chemical structure of the most active compound, EAPB0503, has led to the synthesis of two compounds, EAPB02302 and EAPB02303, 7 and 40 times more active than EAPB0503 against A375 human melanoma cancer cell line, respectively. The aim of this study was to develop and validate a sensitive and accurate liquid chromatography-electrospray ionization-tandem mass spectrometry method to simultaneously quantify EAPB02303 and its potential active metabolite, EAPB02302, in rat and mouse plasma. Analytes were detected in multiple reaction monitoring acquisition mode using an electrospray ionization detector in positive ion mode. Following a liquid-liquid extraction with ethyl acetate, analytes and internal standard were separated by HPLC reversed-phase on a C18 RP18 Nucleoshell column (2.7μm, 4.6×100mm). The method was validated according to FDA and EMA Bioanalytical Method Validation guidelines. The robustness of the method was assessed by introducing small variations in nine nominal analytical parameters. Statistical interpretation was performed by mean of the Student's t-test. Standard curves were generated via unweighted quadratic regression of calibrators (EAPB02303: 1.95-1000ng/mL, EAPB02302: 7.81-1000ng/mL in rat plasma; EAPB02303: 0.98-1000ng/mL, EAPB02302: 1.95-1000ng/mL in mouse plasma). From the analysis of QC samples, intra- and inter-assay precision and accuracy studies demonstrated %R.S.Ds. <12.5% and percent deviation from nominal concentration <7%. Matrix effects (mean matrix factors from 91.8-108.5% in rat plasma; and from 90.4-102.4% in mouse plasma) and stability assays (recoveries >87%) were acceptable and in accordance with the guidelines. No quantifiable carryover effect was observed. The LLOQs were 1.95ng/mL for EAPB02303 and 7.81ng/mL for EAPB02302 in rat plasma, and 0.98ng/mL and 1.95ng/mL for the two compounds in mouse plasma, respectively. This method was successfully implemented to support a mouse pharmacokinetic study following a single intraperitoneal administration of EAPB02303 in male C57Bl/6 mice. The obtained pharmacokinetic parameters of EAPB02303 would be useful to optimize the dosing and the rhythm of administration for subsequent preclinical in vivo activity studies.

Abstract
In this study, a hydrogen/deuterium (H/D) exchange method using gas chromatography-electrospray ionization/mass spectrometry (GC-ESI/MS) was first investigated as a novel tool for online H/D exchange of multitarget analytes. The GC and ESI source were combined with a homemade heated column transfer line. GC-ESI/MS-based H/D exchange occurs in an atmospheric pressure ion source as a result of reacting the gas-phase analyte eluted from GC with charged droplets of deuterium oxide infused as the ESI spray solvent. The consumption of the deuterated solvent at a flow rate of 2 μL min-1 was more economical than that in online H/D exchange methods reported to date. In-ESI-source H/D exchange by GC-ESI/MS was applied to 11 stimulants with secondary amino or hydroxyl groups. After H/D exchange, the spectra of the stimulants showed unexchanged, partially exchanged, and fully exchanged ions showing various degrees of exchange. The relative abundances corrected for naturally occurring isotopes of the fully exchanged ions of stimulants, except for etamivan, were in the range 24.3-85.5%. Methylephedrine and cyclazodone showed low H/D exchange efficiency under acidic, neutral, and basic spray solvent conditions and nonexchange for etamivan with an acidic phenolic OH group. The in-ESI-source H/D exchange efficiency by GC-ESI/MS was sufficient to determine the number of hydrogen by elucidation of fragmentation from the spectrum. Therefore, this online H/D exchange technique using GC-ESI/MS has potential as an alternative method for simultaneous H/D exchange of multitarget analytes.
