Introduction

One of the leading causes of death worldwide is tuberculosis (TB), a highly contagious disease spread through the air. Prior to the SARSCoV- 2 (COVID-19) pandemic, TB was the most common infectious disease-related fatality. In 2020, there will be an estimated 1.3 million deaths worldwide among HIV-negative individuals and 214,000 deaths worldwide among HIV-positive individuals. The Coronavirus pandemic has switched long periods of worldwide advancement in decreasing the quantity of individuals who passed on from TB. Due to the existence of multiple forms, including rifampicin-resistant TB, multidrug-resistant TB, and extensively drug-resistant TB, drugresistant TB continues to pose a threat to public health. Due to the rising incidence of drug-resistant tuberculosis, it is essential to develop novel therapeutics with novel modes of action that are unlikely to cross-resist with existing compounds. The cell wall is a defensive and practical connection point between the intracellular and extracellular conditions. Targeting the biosynthesis pathway of the unique components in Mycobacterium tuberculosis' multilayered cell wall has proven to be a successful strategy for TB drug discovery [1].

Improving pharmacodynamic and kinetic properties

Over the past three decades, the development of recombinant therapeutic proteins has revolutionized the pharmacological treatment of many diseases, including cancer and autoimmune conditions. This expansive and quickly developing class of medication is maybe best addressed by helpful antibodies. Multiple applications for antibodybased therapeutics have resulted from advancements in antibody development, production, the identification of novel targets, and unmet clinical needs. Moreover, other recombinant restorative biologics like erythropoietin (EPO) are additionally a significant class of medications for therapeutics. Due to their well-known influence on pharmacokinetic (PK) and pharmacodynamic (PD) properties, posttranslational modifications (PTMs) have received a lot of attention. In particular, numerous investigational and approved recombinant therapeutic proteins have undergone extensive research on glycosylation, a complex PTM that is capable of influencing a variety of molecular properties like protein conformation, binding interactions, stability, and solubility [2].

Atomic docking, DFT, and pharmacokinetic properties

MAPK signaling pathways rely heavily on the protein kinase BRAF. V600E-BRAF is the most notable transformation in BRAF; it was viewed as in 8% of the relative multitude of diseases, like colorectalmalignant growth (10%), melanoma (60%), and thyroid disease (30- 70%). Hence, the V600E-BRAF kinase is a significant objective in overseeing and treating disease ailments. Dabrafenib and vemurafenib are the two inhibitors (particular) of V600E-BRAF that prompt an exceptionally powerful programmed passing of melanoma cells. They were embraced by the US Food and Medication Organization (FDA) for the treatment of late-stage melanoma. A solitary treatment with a V600E-BRAF inhibitor worked on the patient's way of life and endurance rate significantly. However, despite the success of the approved V600E-BRAF inhibitors, resistance to these selective inhibitors developed between 5 and 8 months into treatment. Because resistance to the selective V600E-BRAF inhibitors may lead to new treatments for V600E-BRAF-associated cancers, finding and validating novel candidates is an important area of research. Understanding the tumor's heterogeneity and resistance evolution is essential for this strategy [3]. In addition, costly and time-consuming wet-lab activities are required for the identification and confirmation of lead compounds as well as the evaluation of active binding sites of bioactive targets linked to a particular lead compound.

Materials and Methods

Physical measurements and chemicals

All of the chemicals were purchased from Sigma Aldrich Company, and their purity ranged from 99% to 99.9%. The mobile phase of the reaction was a mixture of benzene and methanol (8:2 volume ratio), and thin-layer chromatography (TLC) was used to monitor its completion. CL-726 computerized hardware (IndiaMART Part Since, Noida, India) was utilized to gauge the dissolving focuses. An attenuated total reflection (ATR) Nicolet iS10 spectrophotometer for FTIR studies, a diamond crystal) accessory was utilized. Each spectrum contained 32 scans, each with a spectral resolution of 4 cm-1 and a range of 4000–500 cm1. A JEOL ECP400 NMR spectroscope (Tokyo, Japan) was utilized to record 1H and 13C-NMR spectra at 400 MHz. The EA 300 (C.H.N.S.) Element analyzer was used to perform the compounds' elemental microanalysis [4].

Physicochemical and ADME properties

SwissADME is a web instrument that is used to process the physicochemical qualities as well as to foresee the pharmacokinetic properties, ADME boundaries. In addition, it aids in drug discovery by predicting the medicinal chemistry and drug-like nature of compounds. The following physicochemical properties of the synthesized isoxazolidines were investigated: 1) MW > 500 g/mol and a molecular weight of 150 g/mol 2) Acceptors of Hydrogen Bonds 10; ( 3) 0 < number of rotatable bonds < 9; ( 4) Hydrogen Bond Benefactors <5; ( 5) INSTITUTU: 0.25 < part of Csp3 < 1; ( 6) the contrast: 20 Å2 < topological surface region (TPSA) < 160 Å2. The blood-brain barrier permeation (BBB), human gastrointestinal absorption (GI), skin permeability parameter, plasma P-glycoprotein protein binding (Pgp), and interaction of the synthesized compounds with five important human cytochromes (P450) enzymes CYP1A2, CYP2D6, CYP2C19, CYP3A4, and CYP2C9 (the enzymes responsible for 90% of drug metabolism) as well as interfering the medication similarity highlights and restorative science are introduced in Table 3 for all subordinates. Additionally, the bioavailability radar was carried out by observing the pink area in the plot, which represents the ideal range for each characteristic. The molecule has drug-like properties if the molecule's radar plot's pink zone is completely in the red zone. The Bubbled Egg model was likewise used to assess pharmacokinetics [5].

Pre-docking readiness

Both orchestrated compounds (ligands) and protein were ready, limited, and advanced utilizing MOE programming. By utilizing the manufacturer module of MOE, the 3D designs of ligands were fabricated, 3D-protonated, halfway charge was applied, energy was limited by applying MMFF94x force field with RMS slope of 0.05 kcal/ mol/A2, and arranged ligands were saved as a data set record in the MOE structure. The objective construction (PDB: 2X3F) was arranged following the definite strategies depicted before, water particles, B chain, and SO4 were erased, 3D protonation was finished, energy minimization was applied, and 4464 iotas were remedied. The dynamic site of protein was alloted utilizing the MOE programming's site locater module [6].
