For almost five decades, from its application in preserving blood plasma to stabilizing pharmaceuticals and biopharmaceuticals, lyophilization has been used in life sciences. Lyophilization is a popular drying technique for preserving various drugs, formulations and biological materials such as proteins, plasma, and living cells. The researchers have made significant efforts to develop lyophilized nanoparticulate drug delivery formulations. During lyophilization, biological products and vaccines could be increased by removing solvents and the shelf-life of injectables. Thus, lyophilization unstable or heat-sensitive drugs/biologicals can be dried at low temperatures without damaging their physical structure. Lyophilized products can be reconstituted quickly and easily, improving shelf life and easy transportation. Vast applications of lyophilization in the Pharmaceutical Area established the importance of lyophilization techniques in the pharmaceutical field. The present review aims to update recent and advanced applications of Lyophilization techniques in Pharmaceuticals and biological products such as Antibiotics, Vaccines, proteins, enzymes, and...

A series of novel (Z)-3-((5-(2-((E)-arylidene) hydrazine-1-carbonyl)-4-methylthiazol-2-yl)amino)-2-cyano-3-(methylthio) acrylate 4a-t molecules have been synthesized and characterized by 1H NMR, 13C NMRand mass spectral analysis. Starting from ethyl 2-amino-4-methylthiazole-5-carboxylate 1 was reacted with hydrazine hydrate to obtain carbohydrazide molecule 2. Furthermore, reaction of molecule 2 with various aldehyde and the adduct 3a-t formed was reacted with ethyl 2-cyano-3,3-bis(methylthio) acrylate to get novel thiazole derivatives 4a-t, furthermore it was reacted with lithium hydroxide to form acid containing novel thiazole molecule 5a. The significant features of this reaction procedure are novel, easy and less time consuming with analytically pure product...

Numerous disorders are caused by inflammation, and recent epidemics have prompted public health concerns. The fact that there are so many anti-inflammatory medications available doesn’t change the fact that they frequently don’t work because they pose a severe risk of gastrointestinal toxicity with both acute and chronic use, hematologic toxicity with acute use, and nephrotoxicity with chronic use. Curcumin’s clinical value was, however, constrained by its low absorption. Therefore, it is crucial to find new anti-inflammatory medications, and natural products are a great place to start. One such natural substance, curcumin, is a promising therapeutic candidate because of its stability, solubility, and low toxicity. Research has indicated its inhibitory effect on prostaglandin E2 and COX-2 protein formation, as well as on phorbol ester- and CD-induced COX-2 mRNA expression and PGE2 synthesis, among other things. The mechanisms either entail inhibiting cyclooxygenases (COX) and other inflammatory enzymes. This study covers the current state of knowledge with an emphasis on the anti-inflammatory properties of curcumin and their potential molecular...

The whole plant of Biophytum reinwardtii (Zucc.) Klotzsch (BR) and Biophytum veldkampii A.E.S. Khan & et al. (BV) were evaluated for their antioxidant activities, total phenolic content (TPC), and total flavonoid content (TFC). The plants were successfully extracted with varying polarity solvents like pet ether, chloroform, ethyl acetate, and ethanol. Phytochemical evaluation of various extracts revealed the occurrence of alkaloids, carbohydrates, phenolic compounds, tannins, and flavonoids. The TPC was estimated by the Folin-Ciocalteu method and indicated that the maximum amount was present in ethyl acetate extract of BV (61.06 mg of GA/g of extract) followed by BR (60.08 mg of GA/g of extract). The TFC was highest in the ethyl acetate extract of BV (106.67 66 mg of RU/g of extract), followed by BR (96.66 mg of RU/g of extract). In in-vitro studies, ethyl acetate extract showed maximum activity. For BR, the IC50 value of DPPH radical, Nitric oxide radical, ABTS radical, Superoxide radical, and Hydrogen peroxide radical scavenging activity was found to be 48.95, 60.72, 54.85, 58.53, and...

Since ancient times, plants have been used for medicinal purposes for their various therapeutic potentials and safest to modern allopathic medicines. Regularly phytochemicals are proving to be modern medicine with novel drug delivery systems by treating different diseases and disorders. Phytochemical compounds need improvement of efficacy and patient’s compatibility to deliver in various diseases, e.g., high blood pressure, microbial, coronary heart disease, cancers, diabetes, inflammation, etc., also require a rational approach. Nanotechnology is a promising drug delivery approach for targeted or site-specific phytoconstituent delivery. Especially, Nanogels are the most rational approach for targeting skin diseases and enhancing bioavailability. Phytoconstituents or plant extract-loaded nanogels have been reported in in-vitro and in-vivo activities for different skin disorders like aging, acne, skin infection, etc. Nanogels, as a novel drug delivery system, may reduce toxicity and improve the bioavailability of the incorporated drug. The present review is focused on various phytomedicines that have been used in treating skin aging and acne, nanogel formulations prepared, and the effectiveness of both phytochemicals and nanotechnology for...
