Current Advancements on Oral Protein and Peptide Drug Delivery Approaches to Bioavailability: Extensive Review on Patents.

Protein and peptide-based drugs have greater therapeutic efficacy and potential application and lower toxicity compared to chemical entities in long-term use within optimum concentration as they are easily biodegradable due to biological origin. While oral administration is preferable, most of these substances are currently administered intravenously or subcutaneously. This is primarily due to the breakdown and poor absorption in the GI tract.

Green Chemistry Approach for the Synthesis of Isoxazole Derivatives and Evaluation of their Anti-epileptic Activity.

Background: Green strategy involves the design, synthesis, processing, and use of chemical substances by eliminating the generation of chemical hazards. This approach focuses on atom economy, use of safer solvents or chemicals, consumption of energy, and decomposition of the chemical substances to non-toxic materials which are eco-friendly.

Objective: So, the microwave irradiated heating method is considered a green and sustainable technique for the development of novel heterocyclic scaffold-like isoxazole derivatives via chalcones.

Multi-target Polypharmacology of 4-aminoquinoline Compounds against Malaria, Tuberculosis and Cancer.

Background: Polypharmacology means drugs having interactions with multiple targets of a unique disease or many disease pathways. This concept has been greatly appreciated against complex diseases, such as oncology, CNS disorders, and anti-infectives.

Methods: The integration of diverse compounds available on public databases initiates polypharmacological drug discovery research.

Repurposing of Chemotherapeutics to Combat COVID-19.

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) is a novel strain of SARS coronavirus. The COVID-19 disease caused by this virus was declared a pandemic by the World Health Organization (WHO). SARS-CoV-2 mainly spreads through droplets sprayed by coughs or sneezes of the infected to a healthy person within the vicinity of 6 feet.

SEDDS Basic Design and Recent Formulation Advancement: A Concurrent Review.

In the present scenario, lipid-based novel drug delivery systems are the area of interest for the formulation scientist in order to improve the bioavailability of poorly water-soluble drugs. A selfemulsifying drug delivery system (SEDDS) upon contact with the gastrointestinal fluid, forms an o/w emulsion. SEDDS has gained popularity as a potential platform for improving the bioavailability of the lipophilic drug by overcoming several challenges.

Analytical Quality by Design Based Systematic Development and Optimization of a Sensitive Bioanalytical Method for Estimation Cinacalcet HCl in Rabbit Serum.

Context: There is no straightforward method for estimating cinacalcet HCl in biological materials such as serum exists. As a result, the goal of this research is to develop a simple quality by design (QbD) enabled reverse phase-Ultra-Fast Liquid Chromatography (RP-UFLC) model for analyzing cinacalcet HCl in serum.

Aim: The current study envisages the development and validation of an isocratic simple, precise, and rapid QbD enabled RP-UFLC method for the quantification of cinacalcet HCl in both solution form and blood samples.

QbD-based Formulation Optimization and Characterization of Polymeric Nanoparticles of Cinacalcet Hydrochloride with Improved Biopharmaceutical Attributes.

Objectives: The aim of the present work was to prepare QbD enabled optimization, and to improve the oral bioavailability of freeze-dried polymeric nanoparticles of cinacalcet hydrochloride manufactured by nanoprecipitation and ultrasonication methods using polymers PLGA, and poloxamer-188.

Materials And Methods: The initial screening and optimization were carried out for the formulations by employing Taguchi and Box-Behnken Designs. The FT-IR and DSC revealed no interactions and had no incompatibility among the selected drug and polymers.

Exploring the COVID-19 Potential Targets: Big Challenges to Quest Specific Treatment.

Background: The novel strain SARS-CoV-2 of coronavirus diseases (COVID-19) became pandemic at the end of 2019 with an unprecedented global crisis by infecting around 11 million people in more than 200 countries. The condition has now been provoked by the demand, supply, and liquidity shocks that COVID-19 has attacked the lives of a vast population.

Objectives: Researchers are therefore trying to encode and understand the viral genome sequence along with various potential targets to explore the transmission mechanism and the mode of treatment for COVID-19.

Quality by Design Enabled Development of Oral Self-Nanoemulsifying Drug Delivery System of a Novel Calcimimetic Cinacalcet HCl Using a Porous Carrier: In Vitro and In Vivo Characterisation.

In this present research, work quality by design-enabled development of cinacalcet HCl (CH)-loaded solid self-nanoemulsifying drug delivery system (S-SNEDDS) was conducted using a porous carrier in order to achieve immediate drug release and better oral bioavailability. Capmul MCM (CAP), Tween 20 (TW 20) and Transcutol P (TRP) were selected as excipients. Cumulative % drug release at 30 min (Q30), emulsification times (ET), mean globule size (GS) and polydispersity index (PDI) were identified as critical quality attributes (CQAs).
