Abstract
5-Aminoisoquinoline (5-AIQ) is a water-soluble, potent and selective Poly (ADP-ribose) polymerase 1 (PARP-1) inhibitor, widely used as a biochemical and pharmacological tool to study the inhibitory effect of PARPs enzyme. In this study, a simple, selective and reliable ultra-performance liquid chromatography-tandem mass spectrometry assay has been developed for the quantitative analysis of 5-AIQ in plasma using pantoprazole as an internal standard (IS). Both 5-AIQ and IS were separated on an Acquity CSH18 (2.1 × 100 mm; 1.7 µm) column after chromatographic elution of mobile phase comprising of 10 mM ammonium acetate and acetonitrile (35:65; v/v) at a flow rate of 0.3 mL/min. Electrospray ionization in positive mode was used for sample ionization and precursor to product ion transitions of 145.0 > 91.0; 145.0 > 117.4 for 5-AIQ and 384.0 > 138.1 for IS were used for detection and quantification in multiple reaction monitoring mode. The assay was linear in the concentration range of 1.0 to 666 ng/mL with correlation coefficient of ≥0.995. The precision and bias were within the acceptable limits of ≤12.68% and −8.6 to 5.9%, respectively, with mean recovery of 79.1% from plasma and negligible matrix effects (92.4%). In silico ADME prediction, 5-AIQ showed to be very soluble in water and high gastrointestinal absorption along with blood–brain barrier (BBB) permeability. The validated assay was successfully applied in a metabolic stability study, and 5-AIQ was moderately metabolized by human liver microsomes with an in vitro half-life of 14.5 min and intrinsic clearance of 47.6 µL/min/mg. The validated method can be utilized for future pharmacokinetic and bio-distribution studies.

Abstract
Introduction:
Ultra-Performance Liquid Chromatographic (UPLC) method enables analyst
to establish an analysis at higher pressure than High Performance Liquid Chromatographic (HPLC)
method towards liquid chromatographic methods. UPLC method provides the opportunity to study a
higher pressure compared to HPLC, and therefore smaller column in terms of particle size and internal
diameter are generally used in drug analysis. The UPLC method has attracted gradually due to its advantages
such as short analysis time, the small amount of waste reagents and the significant savings in
the cost of their destruction process. In this review, the recent selected studies related to the UPLC
method and its method validation are summarized. The drug analyses and the results of the studies
which were investigated by UPLC method, with certain parameters from literature are presented.
Background:
Quantitative determination of drug active substances by High-Performance Liquid
Chromatography (HPLC) from Liquid Chromatography (LC) methods has been carried out since the
1970's with the use of standard analytical LC methods. In today's conditions, rapid and very fast even
ultra-fast, flow rates are achieved compared to conventional HPLC due to shortening analysis times,
increasing method efficiency and resolution, reducing sample volume (and hence injection volume),
reducing waste mobile phase. Using smaller particles, the speed and peak capacity are expanding to
new limit and this technology is named as Ultra Performance Liquid Chromatography. In recent years,
as a general trend in liquid chromatography, ultra-performance liquid chromatography has taken the
place of HPLC methods. The time of analysis was for several minutes, now with a total analysis time
of around 1-2 minutes. The benefits of transferring HPLC to UPLC are much better understood when
considering the thousands of analyzes performed for each active substance, in order to reduce the cost
of analytical laboratories where relevant analysis of drug active substances are performed without
lowering the cost of research and development activities.
Methods:
The German Chemist Friedrich Ferdinand Runge, proposed the use of reactive impregnated
filter paper for the identification of dyestuffs in 1855 and at that time the first chromatographic method
in which a liquid mobile phase was used, was reviewed. Christian Friedrich Chönbein, who reported
that the substances were dragged at different speeds in the filter paper due to capillary effect, was
followed by the Russian botanist Mikhail S. Tswet, who planted studies on color pigment in 1906.
Tswet observes the color separations of many plant pigments, such as chlorophyll and xanthophyll
when he passes the plant pigment extract isolated from plant through the powder CaCO3 that he filled
in the glass column. This method based on color separation gives the name of "chromatographie"
chromatography by using the words "chroma" meaning "Latin" and "graphein" meaning writing.
Results and Conclusion:
Because the UPLC method can be run smoothly at higher pressures than the
HPLC method, it offers the possibility of analyzing using much smaller column sizes and column diameters.
Moreover, UPLC method has advantages, such as short analysis time, the small amount of
waste reagents and the significant savings in the cost of their destruction process. The use of the
UPLC method especially analyses in biological samples such as human plasma, brain sample, rat
plasma, etc. increasingly time-consuming due to the fact that the analysis time is very short compared
to the HPLC, because of the small amount of waste analytes and the considerable savings in their cost.

Abstract
Dufulin is a plant antiviral agent with a novel molecular structure and has been used widely to prevent and control tobacco and rice viral diseases. In this study, an UHPLC-MS/MS method was developed for rapid determination of dufulin racemate ( rac-DFL) and its R ( S)-enantiomers in rat plasma, tissues, urine, and feces. A MALDI-MSI method was further used for visual research on tissue distribution after intragastric administration of the three analytes. Toxicokinetic study showed that both ( R)-enantiomer of dufulin (( R)-DFL) and ( S)-enantiomer of dufulin (( S)-DFL) had a faster ability to reach Cmax than that of rac-DFL. ( R)-DFL and ( S)-DFL had a similar T1/2, though both were significantly lower than rac-DFL. Cmax of rac-DFL was obviously higher than ( R)-DFL or ( S)-DFL. Meanwhile, Cmax of ( S)-DFL was only about 60% of ( R)-DFL. Rac-DFL and its R ( S)-enantiomers had a dose-dependent toxicokinetic profile. Tissue distribution results revealed rac-DFL, ( R)-DFL, and ( S)-DFL mainly distributed in the liver and kidney, but the maximum concentration was only ng/g grade and could significantly degrade within 3 h. This indicates that dufulin does not cause liver and kidney toxicity in animals. In addition, rac-DFL and its R ( S)-enantiomers have not been detected in brain tissue. Cumulative excretion of rac-DFL and its R ( S)-enantiomers within 24 h in urine and feces were less than 22.85% indicating that they mainly excreted as metabolites. These results could provide evidence for the in-depth toxicity evaluation of dufulin pesticide. In addition, its metabolic selectivity information in vivo has also been obtained.

Abstract
A thalidomide analog, (4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-N'-[(4-ethoxyphenyl) methylidene] benzohydrazide), has been identified as a promising broad-spectrum anti-inflammatory agent in previous study. In this study, a sensitive and selective UPLC-MS/MS assay was developed and validated for its determination in rat plasma samples. The chromatographic separation was performed on an Aquity BEH C18 column using mobile phase comprising of acetonitrile and 10 mm ammonium acetate in the ratio of 85: 15, at flow rate of 0.3 mL/min. The detection and quantification were performed in positive multiple reaction monitoring mode by parent to daughter ion transition of 414.06 ˃ 148.05 for analyte and 411.18 ˃ 191.07 for internal standard (risperidone), respectively using electrospray ionization source. The sample extraction process consisted of liquid-liquid extraction method using diethyl ether as the extracting solvent. The assay was validated by following FDA guidelines and all parameters were found to be within acceptable limits. The linearity was between 10.1 and 2500 ng/mL and the lower limit of quantification was 10.1 ng/mL. The reported results indicate that the assay could meet the requirement for analysis of this compound in amounts expected to the present in actual samples. Further, in vitro metabolic stability study was performed in rat liver microsomes by using the validated assay.
