Research on secondary metabolites of the oyster endophytic fungus Penicillium griseofulvum QDYM-3 and their anti-Alzheimer's disease activity.
(PubMed, Nat Prod Res)
- "Five compounds were isolated from the fermentation broth of the oyster endophytic fungus Penicillium griseofulvum QDYM-3, including 1,6-dihydroxy-3-methoxy-8-methylxanthone (1), (+)-griseofulvin (2), (4 R,5R,6R)-4,5-dihydroxy-6-(6'-methylsalicyloxy)-2-methyl-2-cyclohexen-1-one (3), 3-hydroxybenzyl alcohol (4), and epigriseofulvin (5)...Notably, 1 µg/mL of compound (3) reduced ROS levels by 26.87%, the enzymatic activities of SOD, CAT, and GSH were elevated by 13.97%, 20.74%, and 82.27% respectively, while the level of MDA was reduced by 20.42%. Additionally, the expression of intracellular proteins p-Akt, p-GSK-3β and β-catenin were up-regulated by 57.9%, 50.8% and 40.4%, respectively, at a sample concentration of 5 μg/ml compared with the injury group."

GD06 Terbinafine-resistant Trichophyton indotineae: an analysis of confirmed cases in our regional National Health Service board.
(PubMed, Br J Dermatol)
- "Of the 10 positive mycological culture samples, three were terbinafine resistant (three of 10, 30%), 10 of 10 were itraconazole sensitive, seven of 10 were micoconazole sensitive, two of 10 were voriconazole sensitive and one of 10 was griseofulvin sensitive. Our findings confirm that terbinafine-resistant T. indotineae has been detected in our regional NHS board, and identified strains appeared to be sensitive in vitro to alternative antimycotics (although they may still be clinically resistant in practice). Globally, all dermatologists should be aware of this emerging organism, perform mycological testing if suspecting a dermatophytosis and liaise with local microbiology teams where terbinafine resistance is confirmed, to allow correct treatment and national monitoring."

Particle-Size-Determined Crystallization and Dissolution Behavior of Amorphous Griseofulvin.
(PubMed, Pharm Res)
- "Particle size was found to play dominant role in the dissolution kinetics, whereas the difference in the dissolution rates of the crystalline and amorphous particles was rather negligible. This is a beneficial finding, considering the very low stability of finely powdered amorphous griseofulvin, but at the same time, it negates the primary purpose of amorphization. Main benefit is thus that of the coarse amorphous griseofulvin powder, which can be utilized to fine-tune the dissolution profile due to its delayed dissolution."

Characterization of Different Copovidone Grades as Carrier Materials in Hot Melt Extrusion of Amorphous Solid Dispersions.
(PubMed, Pharmaceutics)
- "The two model drugs itraconazole and griseofulvin were used to examine drug dissolution and degradation during HME via in-line UV-vis spectroscopy. When comparing both polymers, PS-630U offers various advantages due to the improved powder feeding behavior and reduced yellowing of extruded products while maintaining similar melt properties and drug compatibility compared to PS-630. These findings support the use of PS-630U as an optimized copovidone grade for ASD manufacturing, facilitating improved processing characteristics and best product qualities without the requirement of significant formulation adjustments."

Voriconazole is effective in totally drug resistant cases of dermatophytosis
(EADV 2025)
- "Dermatologists in India routinely advise higher dose & longer duration of currently available oral antifungals like terbinafine, fluconazole, griseofulvin & itraconazole. Voriconazole is effective even in the totally drug-resistant cases of dermatophytosis. If used consistently in a greater number of cases, the price of the drug may come down & morbidity is reduced."

Tackling resistant dermatophytosis: A rising challenge
(EADV 2025)
- "The patient was initially put on local and oral Terbinafine 250 mg/d for 2 months, then switched to Griseofulvin 1 g/d, with no improvement, prompting the introduction of Itraconazole 400 mg/d...Voriconazole has also demonstrated efficacy, while terbinafine has shown reduced response rates... Classic dermatophytosis manifest as erythematosquamous lesions, typically localized on the face, trunk, limbs, and large folds. However, the emergence of Trichophyton indotineae, a terbinafine-resistant strain, complicates the diagnosis and treatment of these infections. Initially identified in India and Nepal, this species' resistance is due to mutations in the squalene epoxidase gene, leading to extensive and refractory dermatophytosis, often following inappropriate self-medication with corticosteroids and/or antifungals."

Clinical and Laboratory Characteristics of Trichophyton Indotineae Infection in a National Tertiary Dermatology Centre
(EADV 2025)
- "Among patients without relapses, treatment included varied combinations of oral terbinafine, itraconazole and griseofulvin (Table 2). In this study, we report the largest cohort of patients with T. indotineae infection in Singapore to date. Patients were predominantly young, with common sites of involvement being the groin and buttocks, and the majority were not immunocompromised. Considering the increasing resistance of T. indotineae to oral antifungals, we propose using distinct culture morphology features to aid its identification when advanced molecular diagnostics are unavailable."

Co-occurrence of Varicella and Tinea Capitis in an 8-year-old child: A diagnostic challenge
(EADV 2025)
- "Management included systemic antifungal therapy with oral griseofulvin (20 mg/kg/day) for six weeks, topical antiseptic care for varicella lesions, and monitoring for secondary bacterial infection... This report illustrates the rare overlapping of varicella and tinea capitis, emphasizing the necessity for thorough dermatological examination, including scalp assessment, even during acute viral illnesses. Dermoscopy proves valuable in diagnosing pediatric mycological infections, highlighting the importance of avoiding attribution of all skin lesions to a single etiology without mycological confirmation. Clinicians should broaden their diagnostic approach in similar clinical scenarios, particularly during epidemic periods or in community settings."
