Doxorubicin (DOXO) is an antineoplastic drug that is used extensively in managing multiple cancer types. However, DOXO-induced cardiotoxicity is a limiting factor for its widespread use and considerably affects patients’ quality of life. Farnesol (FSN) is a sesquiterpene with antioxidant, anti-inflammatory, and anti-tumor properties. Thus, the current study explored the cardioprotective effect of FSN against DOXO-induced cardiotoxicity. In this study, male Wistar rats were randomly divided into five groups (n = 7) and treated for 14 days. Group I (Control): normal saline, p.o. daily for 14 days; Group II (TOXIC): DOXO 2.4 mg/kg, i.p, thrice weekly for 14 days; Group III: FSN 100 mg/kg, p.o. daily for 14 days + DOXO similar to Group II; Group IV: FSN 200 mg/kg, p.o. daily for 14 days + DOXO similar to Group II; Group V (Standard): nifedipine 10 mg/kg, p.o. daily for 14 days + DOXO similar to Group II. At the end of the study, animals were weighed, blood was collected, and heart-weight was measured. The cardiac tissue was used to estimate biochemical markers and for histopathological studies. The observed results revealed that the FSN-treated group rats showed decrease in heart weight and heart weight/body weight ratio, reversed the oxidative stress, cardiac-specific injury markers, proinflammatory and proapoptotic markers and histopathological aberrations towards normal, and showed cardioprotection. In summary, the FSN reduces cardiac injuries caused by DOXO via its antioxidant, anti-inflammatory, and anti-apoptotic potential. However, more detailed mechanism-based studies are needed to bring this drug into clinical use.

The main objective of the proposed work was the development of a thermosensitive gel (containing clove and tea tree oil) for the management of vaginal candidiasis. Both oils have been recommended to be used separately in a topical formulation for vaginal candidiasis. Incorporating two natural ingredients (clove and tea tree oil) into a product give it a broad antimicrobial spectrum and analgesic properties. The two oils were mixed together at a 3:1 ratio and converted into o/w nanoemulsion using the aqueous titration method and plotting pseudo ternary phase diagrams. Further transformations resulted in a gel with thermosensitive properties. To determine the final formulation’s potential for further clinical investigation, in vitro analyses (viscosity measurement, MTT assay, mucoadhesion, ex vivo permeation) and in vivo studies (fungal clearance kinetics in an animal model) were conducted. The current effort leveraged the potential of tea tree and clove oils as formulation ingredients and natural therapeutic agents for vaginal infections. Its synergy generated a stable and effective thermosensitive gel that can be utilized for recurrent candidiasis and other infections.

Background: Rising global mortality due to antibiotic-resistant pathogens necessitates novel antibacterial and antifungal agents. This study focuses on synthesizing gold nanoparticles (GNPs) via tricyclic microwave irradiation (TMI) to combat Multi-Drug-Resistant Bacteria and Fungus. The demand for sustainable synthesis methods has led to the exploration of TMI for GNP production. Results: Characterization demonstrates consistent, uniform, and dispersed GNPs with trigonal and hexagonal shapes. GNPs sized 20–55 nm exhibit superior antibacterial and antifungal activity, particularly against drug-resistant Gram-positive bacteria. Notably, GNPs display consistent efficacy against drug-resistant fungus and demonstrate potential for broad-spectrum antimicrobial applications. Conclusion: TMI-synthesized GNPs, characterized by their favorable physical properties and size-dependent efficacy, show promise as effective agents against drug-resistant pathogens. Their ability to combat Gram-positive bacteria, Gram-negative bacteria, and drug-resistant fungus positions them as valuable tools in biomedical sciences. By addressing the urgent need for novel antimicrobial agents, TMI-synthesized GNPs offer a sustainable solution to the escalating global health challenge of antibiotic resistance.

This review of thiazolidinedione or glitazone, which have a five-membered heterocyclic ring C₃NS, shows their versatile properties in terms of pharmacological actions such as antimicrobial, antifungal, insecticidal, pesticidal, antidiabetic, anti-inflammatory, anti-proliferative, anti-neurotoxicity, anticonvulsant, anti-thyroidal, and anti-tubercular uses. While having a wide range of biological activities, the TZDs mainly act via binding to the peroxisome proliferator-activated receptor (PPAR) members. PPAR-γ are ligand-activated transcription factors, which are members of the nuclear hormone receptors group. Activations of PPAR-γ regulate cell proliferation and differentiation, glucose homeostasis, apoptosis, lipid metabolism, and inflammatory responses. This review explores the synthesis of a thiazolidinedione and its derivatives, focusing on their pharmacological profiles and antidiabetic activity. It highlights the benefits of synthesis, reaction profiles, and catalyst recovery, which may encourage further investigation into these scaffolds by researchers. Based on synthesized derivatives, some glimpses of the structure–activity relationships of some compounds have been compiled. All the synthesized derivatives have been reviewed concerning their standard drugs already available and concluded with the highly or moderately active synthesized derivatives of thiazolidinedione. The data for this review was collected by an extensive review of current scientific literature, including on the synthesis, biological evaluation, SAR, and patents (2015–25).

A newly UHPLC-MS/MS method development and validation for S-Allyl Cysteine was used to evaluate the comparative pharmacokinetic parameters. SC PLGA NPs (S-Allyl Cysteine Poly (D,L-lactide-co-glycolic acid) Nanoparticles) were developed by the emulsion solvent evaporation method. SC PLGA NPs showed their drug loading and encapsulation efficiency to be 5.13 ± 0.10% and 82.36 ± 4.01%, respectively. SC PLGA NPs showed a spherical morphology of an average size (134.8 ± 4.61 nm), PDI: 0.277 ± 0.004, and −25.3 ± 1.03 mV Zeta-Potential (ZP), and is suitable for oral delivery. The development and validation of the UHPLC-MS/MS bioanalytical method were performed successfully for PK-parameter examinations with 1.219 min RT, MS (162.00/73.10), and a total run-time of 2.0 min. Additionally, 1.0–1000.0 ng/mL was a linear range with inter- and intra-day accuracy of 92.55–99.40%, followed by a precision of 1.88–4.23%. SC PLGA NP’s oral bioavailability was significantly higher (** p < 0.01) in comparison to the SC-S treated groups’ (iv and oral). The antimicrobial activity of SC PLGA NPs proved to be more effective than pure S-Allyl-L-Cysteine with significant results (p < 0.01) in comparison to SC-S. SC PLGA NPs showed fitted physicochemical and enhanced antimicrobial properties, which can be helpful for oral administration. Based on the proposed research results, SC PLGA NPs were used for the improvement in oral bioavailability with a sustained and controlled release of S-Allyl-L-Cysteine delivery.
