ABSTRACT: Symmetric peak and effective peak resolution in chromatography were achieved by adjusting the mobile phase's pH and amount of organic Phase. The retention time of 2.127 and 4.145 minutes was observed after the elution of Bortezomib and Selinexor respectively. To accurately measure both Selinexor and Bortezomib at the same time, an approach was developed with an optimal wavelength of 236nm. Selinexor and Bortezomib were successfully separated by chromatography using a mobile phase of Acetonitrile: 0.1% Formic acid (30:70, v/v) and Luna Phenyl Hexyl (250×4.6mm, 5μ) column running at 1.0 ml/min. When looking at the linearity range, statistics correlating 0.999 indicates a very excellent correlation. For intermediate precision intervals, the relative standard deviation of Selinexor and Bortezomib, respectively, was 0.47 and 0.53, indicating the reproducibility of the analytical approach. The suggested analytical approach has a low LOD, which means that it is also extremely sensitive. This indicates that the suggested approach has sample accuracy by ICH requirements, as 99.9 and 100.2 percent of the spiking Selinexor and Bortezomib, respectively, were recovered. According to ICH recommendations, forced degradation of under twenty per cent is acceptable. Selinexor and Bortezomib showed degradation of under 20 percent using the suggested approach, which indicates stability.

INTRODUCTION: Xpovio, also known as Selinexor, is a medication used to treat cancer by selectively inhibiting nuclear export. This mechanism operates by inhibiting the function of exportin 1, thereby preventing the movement of various proteins responsible for promoting the growth of cancer cells from the nucleus to the cytoplasm. As a result, the cell cycle is halted, leading to programmed cell death 2. This drug has a unique mechanism of action 3, 4.
Bortezomib is a dipeptide boronic acid derivative and proteasome inhibitor that is commonly prescribed for the treatment of multiple myeloma and mantle cell lymphoma 5.
This protein complex, known as the 26S proteasome, plays a crucial role in breaking down ubiquitinated proteins through the ubiquitin-proteasome pathway.
It is believed that bortezomib primarily works by reversibly inhibiting the 26S proteasome, which leads to cell cycle arrest and apoptosis in cancer cells. There may be multiple mechanisms at play in the anticancer activity of bortezomib 6. Fig. 1 and 2 display the molecular structure of Selinexor and Bortezomib, respectively.

MATERIALS AND METHOD:
Chemicals and Reagents: Samples of Selinexor and Bortezomib were supplied as the reference material by Supriya Labs in Mumbai. All compounds, including HPLC -grade acetonitrile, Formic acid, were procured from the chemical division of Merck located in Mumbai.
Instrumentation: The investigation was carried out utilizing a high-performance liquid chromatography (HPLC) apparatus comprised of a Waters e 2695 Shimadzu column, a photodiode array (PDA) detector, and Empower software version 2.0 as its driver. a UV detector, a Shimadzu UV-visible spectrophotometer, and a Phoenix 4.5 L digital ultrasonic cleaner was utilized.
Selinexor and Bortezomib Stock Solution: Weigh out precisely 100 mg of Selinexor and 10 mg of Bortezomib for the working standard. Then, transfer the contents to a 100 mL volumetric flask that has been diluted with diluent to volume.
Selinexor and Bortezomib Standard Solution: Take 5 ml of the stock solution of Selinexor and Bortezomib and transfer it to a 50 ml volumetric flask. Next, dilute the solution with the appropriate diluent until the flask is filled to the desired volume.
Selinexor and Bortezomib Sample Solution: Accurately weigh 10 milligrams of Bortezomib and 42.5 mg of Selinexor, then transfer to a 10 ml volumetric flask. To dissolve, add around 7 ml of diluents and sonicate for 20 minutes. Then, dilute with diluent to volume.

Method Development: An in-depth analysis of chromatographic settings, including column type and temperature, mobile phase, and flowing velocity, is essential for optimizing chromatographic methodology, achieving symmetrical peak design, and enhancing resolution. The mobile phase was optimized by trying out numerous mixtures of appropriate solvents, and in the end, Acetonitrile: 0.1% Formic acid (30:70, v/v) was chosen as the optimal mobile phase at a rate of 1.0ml/min. Table 1 displays the optimum chromatographic parameters. Fig. 2 & 3 displayed the blank and optimized chromatogram, respectively.
Method Validation: System suitableness, linearity, accuracy, robustness, precision, and selectivity are only few of the factors that were considered while validating the suggested technique in accordance with ICH Q2R1 recommendations 7-9.
Linearity: According to ICH, linearity is the extent to which the method of analysis yields test findings that scale linearly with the quantity of analyte in the given sample 10, 11. The spectrum of an analyte concentrations, defined as the difference between the highest and lowest concentrations, is an indicator of the analytical method's accuracy, precision, as well as linearity. In order to establish linearity, small portions were prepared and analyzed in threefold throughout an amount range of 25-150μg/ml for Selinexor and 2.50-15.00μg/ml for Bortezomib. By comparing the calibration graph to the linear regression formula, a correlation coefficient was calculated. Fig. 4 and 5 displayed the linearity results.

FIG. 5: CALIBRATION CURVE OF BORTEZOMIB
Precision: Analysis precision was calculated using both intra- and inter-day standards. The RSD is a measure of accuracy 12.
Accuracy: Accuracy is measured by how much data can be recovered. Pre-examined samples are assessed at three concentrations before being spiked with established quantities of standard Selinexor and Bortezomib 13.
LOD and LOQ: According to ICH, the minimum detectable concentration of an analyte (although it is not always its quantitative value) is known as the limit of detection. The minimal detectable concentration of a component in a sample using an appropriate analytical technique is called the LOQ. The LOD and LOQ were calculated through data from a calibration graph.
Forced Degradation Studies: Using forced degradation studies (FDS), the stability-indicating characteristic of the proposed approach was evaluated. A range of conditions were used for the experiments, including thermal degradation, oxidative hydrolysis, acid hydrolysis, alkaline hydrolysis, and photolysis (UV energy-days/dark control). The stability of Selinexor and Bortezomib was evaluated by exposing them to FDS under various stress conditions 14, 15.
RESULTS AND DISCUSSION:
Chromatographic Optimization: After carrying out a series of experimental protocols, it was noted that the mobile phase, which comprised 30:70 of acetonitrile and 0.1% Formic acid displayed a peak characterized by desirable theoretical plate count, resolution, and tailing factor. Therefore, this procedure was optimised and validated.
Specificity and Selectivity: The procedure’s specificity and selectivity were assessed by looking for interference peaks in the chromatograms of placebo and blank samples. In the retention time ranges, the HPLC chromatograms for the drug matrix (a mix of the Drug and placebos) revealed almost no interference peaks. As a result, the HPLC approach presented in this study was restricted.
Linearity: Both Selinexor (y = 31387.33x + 21904.04) and Bortezomib (y = 32255.90x + 1300.61), when tested across the dosage ranges of 25-150 μg/ml and 2.50-15.00 μg/ml, correspondingly, were found to have linear concentration-response relationships.

Findings for limits of detection, limits of quantification, and accuracy were all within the permitted limits during validation, demonstrating that the instrument can provide reliable findings down to very low concentrations. Peaks in degradation may be identified in research.
