The development of new heterocyclic frameworks with enhanced pharmacological potential remains a fundamental goal in medicinal chemistry. In this study, a novel series of spiro-thiazolidinone and thiopyrimidone hybrids were designed and synthesized through multistep condensation reactions involving dimedone, aromatic amines, and thioglycolic acid. The synthesized compounds were structurally characterized using FT-IR, ¹H NMR, and ¹³C NMR spectroscopic techniques, confirming the successful formation of the targeted heterocyclic systems. The molecular structures were further supported by their

In the context of this project, a novel and eco-friendly process system was established for the purpose of dye removal from water. The X-ray diffraction (XRD) characterization of the catalyst revealed the presence of multiple mineralogical phases, including calcite, Filipstadite, eucryptite, geothite and cristobalite. Subsequent elemental chemical analysis by X-ray Fluorescence Spectrometer (SFX) revealed a substantial presence of iron oxide (31.41 %) and cristobalite (37.42 %).
Read MoreThe current study focuses on the pollution of the Netravathi River, Gurupura River, and Baggundi Lake in the Dakshina Kannada District, which is highly polluted as a result of illegal or unauthorized discharge of domestic wastewater into these rivers. A study was carried out to assess the quality and quantity of sewage water generated in the Baikampady Industrial Area, Mangaluru, alongside an initial survey to examine the types and nature of industries operating within the area. Sewage water samples were collected from 20% of industries in each category; i.e., treated sewage and untreated sewa
Read MoreTreatment of industrial wastewaters by conventional methods requires skilled labours, external energy, high operation cost and maintenance cost, thereby creating a need for efficient eco-friendly and less expensive treatment method. The Present study focuses on treatment of industrial wastewater from paper and pulp industry, textile industry and pharmaceutical industry by using soil biotechnology. The lab scale model was set up using granular media like soil, sand and gravels. The experiments for treatability study were carried out with and without earthworms. The Eisenia fetida Earthworms wer
Read MoreThe purpose of this study was to explore the impact of two different extraction times (15 min and 30 min) on the extraction yield of phytochemicals and antioxidant activity of various Benjakasorn formula mixed with Chamomile, Goji berry and Stevia. Decoction extracts were tested for TPC, TFC, DPPH radical scavenging, and FRAP antioxidant power. Performance of multi-herb preparations was prominent, the highest yield (26%), TPC (145 mg GAE/g), TFC (200 mg QE/g), and FRAP (145 mg TEAC/g) were reached at 30 min for BJKCMLBSR indicating synergistic effect. Single herbs were somewhat inconsistent in
