G Jaya Sheela, M Satya Babu, Pramod Kumar
A selective reversed-phase high-performance liquid chromatography (RP-HPLC) technique was developed for 1α-hydroxy vitamin D2 (Doxercalciferol) related substances analysis. The technique is proficient of eluting various impurities related to process and degradation. To separate both the vitamin D2 Analogs i.e., doxercalciferol and ergocalciferol. HPLC of Shimadzu, provided with autosampler, column oven, quaternary pump and UV detector, were used for development studies. The mobile phase used water and acetonitrile. The diluent used was methanol and detection was examined at wavelength 265 nm. The method is sensitive for doxercalciferol, ergocalciferol, impurity-A and impurity-B; the limit of detection (LoD), value is 0.01% and limit of quantitation (LoQ) value is 0.03%. Linearity of doxercalciferol and related impurities at various concentrations was performed and the obtained correlation coefficient for doxercalciferol is 0.995, ergocalciferol is 0.997, impurity-A is 0.990 and impurity-B is 0.993. The optimized method was validated and demonstrated that the technique is selective, precise, linear, sensitive and accurate. The method is simple, inexpensive and useful for routine testing of doxercalciferol API. In addition, the technique was effectively applied for the elution of both the vitamin D2 Analogs i.e., doxercalciferol and ergocalciferol. Further, the same method is applicable for the determination of assay for these two API’s and the same assay method was validated.

Chronic, recurring, and remitting inflammatory disease with an unknown cause is inflammatory bowel disease (IBD). It is a condition that affects people throughout their lives and has many consequences because it is clinically common. Numerous risk factors are still unknown, and the pathophysiology of IBD is still not fully understood. There are a variety of side effects associated with conventional ulcerative colitis treatment. Globally, there is a rise in the use of herbal therapy for IBD. The medicinal plant Jatropha curcas (L.) belongs to the Euphorbiaceae family. It is a biofuel plant with a few pharmacological effects that have been researched. The study’s purpose was to discover and investigate the bioactive components in an ethanolic extract of J. curcas. The leaves of L. J. curcas were gathered, shade dried, crushed up, and gradually extracted with ethanol using the soxhlet percolation method. By using fourier-transform infrared spectroscopy (FTIR) and high-performance liquid chromatography (HPLC), the phytoconstituents in the Jatropha leaf extract were confirmed. Along with the interpretation of mass spectra, the isolated chemicals were identified by contrasting their peak areas and retention times. Due to the discovery of possible, bioactive components as a result of the current inquiry, we are now able to investigate biological activity. After that, gas chromatography-mass spectrometry (GC-MS) was used to analyze the crude extracts. A large variety of secondary metabolites were detected in the extracts’ profile, which was then spectroscopically described. The presence of phytoconstituents, including flavonoids, tannins, and triterpenoids significantly reduces internal inflammation and lessens damage to the intestinal mucosa. Herbal treatments work through a variety of processes, including immunological control and antioxidant activities.

Cosmetics have fascinated the human race for ages. Cosmetics have been found to benefit in several ways such as enhancing appearance, protection, cleansing etc. If fortified with the benefit of herbal ingredients, these personal care products have proven to be a boon for many. The current study involves the formulation of seven shampoos using different herbal extracts and their comparative investigation for physicochemical and performance characteristics. Various herbal extracts using components such as coffee, fenugreek, green tea, bringaraj, onion seeds, orange oil, and lemon oil were developed and compared against the marketed standard. The effect of various extracts on the parameters such as surface tension, foam test and foam stability test, viscosity, cleansing test, sag test, dirt dispersion, wetting time and pH was successfully tested. All the formulations were found to be beneficial in eliminating oil, dirt, and dandruff, encouraging smooth, silky hair appearance, fortifying and darkening hair without altering or harming hair tresses. Our findings suggest the incorporation of fenugreek, lemon and orange peels to increase the cleansing ability. However, the inclusion of onion seeds and green tea has been found to be beneficial in the generation and stability of the foam.

Nikam Aarti, Kamble Ravindra
Fenofibrate (FF) is a lipid-lowering agent classified in the biopharmaceutics classification system (BCS) class II with lower solubility and higher permeability. This research work deals with developing FF containing liquid self-micro emulsifying drug delivery system (L-SMEDDS) and converting it into solid SMEDDS (S-SMEDDS) using a lyophilization technique followed by the manufacturing of tablets with enhanced solubility and dissolution rate. L-SMEDDS of FF were manufactured using Tween 80, oleic acid, and transcutol. With the help of the lyophilization technique, this L-SMEDDS was converted to S-SMEDDS using microcrystalline cellulose and finally, immediate-release tablets were developed using S-SMEDDS. The L-SMEDDS showed excellent stability due to zeta potential of -1.69 mV and a globule size of 250 μm. The lyophilized S-SMEDDS of FF showed nearly 58-fold solubility enhancement in distilled water in comparison to pure FF due to the formation of amorphous material confirmed in the X-ray diffraction (XRD) study. The F9 formulation showed 100% drug release within 40 minutes with enhanced dissolution properties compared to conventional tablets. The optimized formulation was robust and stable at the accelerated condition for 3 months. The current research work demonstrates lyophilization as a potential approach to convert the L-SMEDSS to a S-SMEDDS with an enhanced solubility and dissolution rate.

Kunal Bagul, Atishkumar Mundada
Class II in the biopharmaceutical classification system, eplerenone (EPL) is a selective aldosterone antagonist. Due to its poor solubility, EPL has limited bioavailability. Here, an innovative spray-drying method was used to transform a water soluble polymer into an amorphous dispersion of the EPL. Different polymer SOL/EPL ratios were tested to determine EPL’s solubility and dissolution enhancement properties. In order to learn more about the physical and chemical properties of this novel amorphous solid dispersion (ASD), methods like powder X-ray diffraction spectroscopy (PXRD), differential scanning calorimetry (DSC), fourier transform infrared spectroscopy (FTIR), particle size distribution (PSD) using a Malvern instrument, and scanning electron microscopy (SEM) were used. There was no chemical interaction between the binary mixture of EPL and SOL which was confirmed from the FTIR spectra obtained. The enhancement in the solubility and dissolution of EPL and binary mixture prepared were due to the amorphous conversion of EPL in the SOL polymer (amorphous solid dispersion), which was confirmed from DSC thermogram, PXRD spectra obtained and was also confirmed from the solubility study, in-vitro dissolution study. Finally, ex-vivo intestinal absorption study performed on the goat intestine using amorphous solid dispersion and pure EPL, also improved intestinal absorption of EPL through amorphous solid dispersion prepared.

The frequency of overweight concerns and obesity is progressively growing in high-income countries in the west and low-income and middle-income countries. Those suffering from these conditions may find that taking measures to cut their carbohydrate consumption and their absorption rate is beneficial. To slow the pace at which glucose is taken into the bloodstream, blocking amylase, a key enzyme in the digestion of carbs, is highly recommended. AIs, or beta-amylase inhibitors, are chemicals found in plants that work to prevent this enzyme from doing its job. Interestingly, the common bean, or Phaseolus vulgaris, has protein-based α‐Amylase inhibitors that regulate the activity of this enzyme through protein-protein interaction. In this article, we cover the numerous extracts of common bean seeds, the protein inhibitors that those extracts include, and what the most recent research has shown about the molecular structure of those extracts and the method by which they exert their inhibitory effects. Evidence for the possible benefits of P. vulgaris protein inhibitors, including clinical research conducted on both animals and humans, is also covered in this article. However, more research is necessary to validate the therapeutic efficacy of the drugs already on the market. This research has the ability to provide a succinct review of the current state of information on P. vulgaris extract and its prospective application as a nutraceutical alternative to control possible weight gain if observed to be successful.

Bacterial cellulose (BC) is a highly purified form of cellulose that offers several benefits, including an ultrafine fiber network, a high water retention capacity, and simple fabrication into desired forms. There has been a recent uptick in BC’s focus on drug delivery for biomedical applications. Studies on prodrug design, controlled-release methods, and pill coating have all been conducted for BC. This research was done to determine if BC might be employed as a medication carrier in chemical and biological formulations. BC microparticles laden with the medication were produced via grinding. Clordiazepoxide hydrochloride (CDP) was used to test the microparticles’ drug loading and release capabilities. Particle morphologies, drug loading efficiency, loaded drug physical state, and drug release behavior were all assessed for the manufactured microparticles. Amorphous microparticles were formed from BC microparticles. An scanning electron microscope (SEM) study found that the microparticles had a nearly round form with an average diameter of 400–500 μm. Drug loading was greater in the renewed BC microparticles (37.57 ± 0.22%) when the concentration of drugs was held constant at 10%. More than 85% of the medication was delivered for all formulations in the first 30 minutes.

Monika Bhairam, Shiv S. Shukla, Beena Gidwani, Ravindra K. Pandey
A recently authorized antiviral drug called dolutegravir has solubility problems and could be a Biopharmaceutical Classification System (BCS) class II candidate. The current study aimed to improve dolutegravir’s solubility and efficiency by employing the solid dispersion method. Different ratios of hydrophilic polymeric carriers, including polyethylene glycol (PEG) 6000, polyvinyl pyrrolidone (PVP) (30K), and hydroxypropyl methylcellulose (HPMC), were used. Dolutegravir (DTG) and soluplus were produced as a solid dispersion at 1:5 ratio using the solvent evaporation method. A variety of techniques were utilized to describe the solid state, including powder X-ray diffraction (XRD), differential scanning calorimetry (DSC), and fourier transform infrared spectroscopy (FTIR). Produced solid dispersion did not reveal any physicochemical interactions between the DTG and soluplus, but the X-ray diffractogram clearly showed that the drug’s crystalline state had transformed to an amorphous state. DTG was released quickly from solid dispersion (92%) compared to pure drug (10.12%), physical mixture (22.06%), and commercially available DTG (62.90%). The formed solid dispersion’s drug release kinetics was in line with the Higuchi Model. Finally, the rapid drug release from the solid dispersion formulation showed higher Cmax (15.25 ± 0.40 μg/mL) compared to the physical mixture (5.11 ± 0.20 μg/mL) and pure drug (4.91 ± 0.73 μg/mL). DTG’s enhanced bioavailability in experimental wistar rats (AUC: 147.99 ± 23.86 μg/h/mL) further supported this when compared to the AUC of animals administered with physical mixture (52.35 ± 4.32 μg/h/mL) and pure drug (43.32 ± 3.13 μg/h/mL). Thus, it could be inferred that by employing the solid dispersion delivery system and the hydrophilic carrier, soluplus, the bioavailability and dissolution profile of DTG could both be improved, which could be expected to improve the drug’s effectiveness in treating HIV/AIDS.

26. Exosomes as Crucial Player in Insulin Resistance and Obesity: Potential Therapeutic Approach
Shreya Sood, Sushma Devi, Thakur G. Singh, Nishant Yadav, Parveen Kumar, Arindam Chatterjee
Increasing obesity has become a serious health problem worldwide in recent years, both in adults and children. Obesity can lead to numerous diseases such as osteoarthritis, diabetes, cardiovascular and respiratory diseases, and other metabolic disorders. In addition, obesity is considered one of the most common causes of insulin resistance in the body. Moreover, obesity disrupts normal insulin physiology, resulting in impaired insulin signaling and other intrinsic abnormalities such as poor glucose movement, phosphorylation, and decreased glucose oxidation and glycogenesis. Therefore, it is necessary to find an effective treatment for such conditions. Recently, exosomal therapy has been proposed as one of the alternative approaches to treat metabolic diseases. Exosomes are endosome-derived extracellular vesicles that circulate in body fluids such as mucus, blood plasma, urea, etc., transfer molecules and signals from one cell to another, and thus are involved in various normal and pathological processes in the human body. It has been discovered that exosomes play a role in processes related to obesity, such as adipocyte differentiation, angiogenesis, inflammation, etc. The current study reviewed exosomes’ role in the development of insulin resistance associated with obesity and possible targets.
