A Comprehensive Review on Plant-based Fluorophores and their Diverse Applications

2026-02-12

Fluorescence, a phenomenon where substances emit light upon excitation, has been largely explored in synthetic materials. However, plants have been harnessing this property for millions of years, with various extracts exhibiting fascinating fluorescent properties. This review delves into the realm of plant extracts displaying fluorescence, highlighting their diverse applications, mechanisms, and potential uses. This study summarizes various classes of fluorescent phytochemicals, including alkaloids, phenolics, and terpenoids, coumarins, anthocyanins, and discusses their excitation and emission spectra. The review also examines the structural dependent functional diversity of plant secondary metabolites influencing fluorescence. Furthermore, the applications of fluorescent plant extracts in fields like biomedicine, food technology, and environmental monitoring in combination with bioimaging, biosensing, and optoelectronics are also highlighted. This comprehensive review aims to spark further research into the untapped potential of fluorescent plant extracts, unlocking new avenues for scientific discovery and innovation.

Recent Advances in the Chemistry of Thienopyranone Heterocycles: Synthesis, Reactivity, and Application

2026-02-12

Thiophene and pyranone are valuable heterocyclic compounds that play a crucial role in the development of new drug molecules. The combination of thiophene and pyranone moieties in hybrid structures has opened exciting possibilities for various applications, leading to the discovery of thienopyranones (Thpyns), such as 5H-thieno[3,2-b]pyran-5-one, 2H-thieno[2,3-b]pyran-2-one, 4H-thieno[3,2-c]pyran-4-one, 7H-thieno[2,3-c]pyran-7-one, all of which exhibit intriguing properties. This review offers an in-depth analysis of the preparation methods and chemical reactivity of thienopyranones.

An Expository Review on the Multifaceted Applications of Sodium Alginate as a Scaffold in Metal-Organic Frameworks

2026-02-12

Polysaccharides like sodium alginate manifest numerous applications due to the characteristics of biocompatibility, low toxicity, adsorption benefits, nature of regenerating tissues, response to pH stimuli, and exemplary binding property with metal ions. Metal-Organic Frameworks (MOFs) absorb and trap toxins/drugs/biosensors to speed mass transfer rates. Sodium alginate features accessible -COOH and -OH functional groups that allow for easy modification with various functional groups. Sodium alginate incorporated Metal-Organic Frameworks (MOFs) significantly enhance its potential, unlocking numerous opportunities for diverse applications across fields such as drug delivery, sensors, and environmental remediation. This modification not only improves the material's functional properties but also reduces systemic toxicity. The filmforming nature with great biodegradability and biocompatibility of the SA@MOF system proves it an appropriate food packaging material with exceptional mechanical and antimicrobial properties, lessening toxicity by avoiding direct contact with food material, amplified water barrier property, and preservation longevity. The SA@MOF outperforms drug delivery, toxic adsorption, antibiotic sensing, food freshness, etc. The SA-MOF-based products like to depict itself as a research-based industry, as the source of innovative drugs, composite films, and toxin absorbents.

An In-depth Analysis of India's API Import Trends in Year 2022-23: Focus on the Top 10 Non-Chinese Sources

2026-02-12

Background: India and China are pivotal players in the global Active Pharmaceutical Ingredient (API) market, and their interdependence is evident through intricate import-export dynamics within the sector. However, this symbiotic relationship faces stiff competition from counterparts in Europe, the USA, and LATAM. Specific factors drive India's procurement of certain APIs from nations beyond China, significantly impacting the economic landscape of Southern Asia. Interpreting these factors that influence import trends in the API market is necessary to strategize the future API demand-supply.

Objective: This review focuses on the top 10 API imports into India in the year 2022-23 from countries other than China. The aim is to provide a comprehensive understanding of these crucial pharmaceutical components, including their applications, mode of action, and industrial synthesis processes. The review also seeks to illuminate diversification initiatives within India's API sector and unravel the reasons behind substantial import trends for each specific API.

Methods: The process of data collection and its subsequent utilization in analyzing the specific surge in API imports in India during the period of 2020-2022 has been done by five distinct subprocesses: (a) data repossession and preprocessing; (b) development analysis of article publications; (c) distribution analysis of articles by subject, country, application, mode of action and synthesis; (d) scientific teamwork analysis among authors; and (e) development and discovery analysis of research topics. In the review, for each API, a framework has been provided that includes application information, synthesis with reaction scheme, price structure, and the reasons for the high import demand.

Results and Discussion: The escalation of import volumes of specific Active Pharmaceutical Ingredients (APIs) into India from sources outside of China can be attributed to several key factors. Among these are the implementation of revised Indian internal policies, approval for drug formulation by authorized agencies, a heightened reliance on bio-enzymatic API synthesis processes within Europe in contrast to China, the establishment of new research centers in India, and a notable surge in the incidence of certain diseases within the country. Additionally, India's burgeoning population, coupled with increased consumption of animal-derived food products, has contributed to heightened demand for APIs sourced from alternative markets than the Chinese market. These factors collectively underscore the complexity of the pharmaceutical supply chain and the various influences driving import dynamics within the Indian market.

Conclusion: A thorough examination of API imports into India during the fiscal year 2022-23 has unveiled significant trends, applications, and underlying rationales driving import patterns. The consolidation of manufacturing processes has provided invaluable insights into the synthetic research pathways associated with each API listed. The data serves as a critical resource for stakeholders within the pharmaceutical sector, facilitating informed strategic decision-making and fostering advancements in India's API industry.
