In this work, we evaluated the antidermatophytic activities of three resorcinol derivatives that have a history of use in dermo-cosmetic applications to discover molecules with multiple dermatological activities (i.e., multi-target drugs), thereby reducing the cost and time necessary for new drug development. The antidermatophytic activities of the three skin lighteners were evaluated relative to the known antifungal drug fluconazole on nine dermatophytes responsible for the most common dermatomycoses: , , , , , , , and . Among the three tested resorcinols, only two showed promising properties, with the ability to inhibit the growth of all tested dermatophytes; additionally, the IC values of these two resorcinols against the nine dermatophytes confirmed their good antifungal activity, particularly for phenylethyl resorcinol against . Ultrastructural alterations exhibited by the fungus were observed using scanning electron microscopy and transmission electron microscopy and reflected a dose-dependent response to treatment with the activation of defence and self-preservation strategies.

Experimental and DFT studies on the green synthesis of 2-amino-4H-chromenes using a recyclable GOQDs-NS-doped catalyst.

This research presents an innovative approach for synthesizing 2-amino-4H-chromene derivatives, utilizing 30 mg of NS-doped graphene oxide quantum dots (GOQDs) as a catalyst in a one-pot, three-component reaction conducted in ethanol. The NS-doped GOQDs were synthesized using a cost-effective bottom-up method through the condensation of citric acid (CA) with thiourea and the reaction was carried out at 185 C, resulting in the elimination of water. The catalytic performance of the synthesized NS-doped GOQDs resulted in high product yields, achieving up to 98% for the 2-amino-4H-chromene derivatives from aromatic aldehydes, malononitrile, resorcinol, -naphthol, and dimedone.

A novel protocol for the synthesis of monoprotected resorcinol -methyliminodiacetate (MIDA) boronates was developed via the chemoselective deprotection of diprotected resorcinol MIDA derivatives with identical protecting groups, utilizing the MIDA boronate moiety as a blocking group for deprotection. This protocol exhibited a broad substrate scope, and the resulting MIDA boronates were readily isolated by simple filtration from the reaction mixture. Furthermore, the utility of this protocol was demonstrated by converting the resulting MIDA boronates into value-added chemicals containing resorcinol scaffolds.

Article Synopsis
- The study utilized click chemistry, specifically CuAAC, to create crosslinked derivatives of hyaluronan-based graft copolymers under mild conditions using ferulic acid and novel azido-terminated crosslinking agents.
- Characterization of the resulting materials was conducted through NMR, TGA, and DSC analyses to assess their structural properties, swelling behavior, and gel-like characteristics.
- The crosslinked materials demonstrated superior swelling performance, shear-thinning behavior, and significantly higher enzymatic resistance compared to commercial viscosupplements, suggesting their potential use as innovative viscosupplements.
Urinary mycoestrogens and gestational weight gain in the UPSIDE pregnancy cohort.
Environ Health

Environmental and Occupational Health Sciences Institute, Rutgers University, 170 Frelinghuysen Road Piscataway, 08854, Piscataway, NJ, USA.
Article Synopsis
- Zearalenone (ZEN), a mycotoxin from Fusarium fungi found in many food supplies, can bind to estrogen receptors and is linked to reproductive issues, yet research on its effects during pregnancy is limited.
- A study measured ZEN levels in urine samples from 286 pregnant women and analyzed their weight gain to determine the impact of mycoestrogens.
- The findings indicated that higher concentrations of ZEN were associated with increased gestational weight gain, particularly in those carrying male fetuses, suggesting that mycoestrogen exposure could influence pregnancy weight dynamics.
Expanding the Diversity of the Cyanobacterial Dialkylresorcinol Bartoloside Family.

Article Synopsis
- Researchers studied cyanobacterial dialkylresorcinol bartolosides, initially thought to have glycosylated and halogenated structures.
- They found that these compounds can form esters through a process involving chlorinated alkyl chains and fatty acids, leading to a variety of bartoloside derivatives.
- The study identified 27 bartoloside and ester variants, including two new types, and revealed new structural features like hydroxylation that were not previously linked to this metabolite group.
