Methoxyfenozide is an insecticide with a unique mode of action on the insect ecdysone receptor and has been registered for the control of insect pests all over the world. In the present work, Spodoptera frugiperda was exposed to sublethal and lethal concentrations of methoxyfenozide to determine its impact on specific biological traits, metabolic enzyme activity, and the expression of detoxification enzymes. The result showed that 72-h posttreatment with LC50 and LC70 of methoxyfenozide significantly reduced the fecundity (eggs/female) of the F0 generation compared to those of the control group.

Candida is a commensal fungus of clinical interest that commonly lives in oral cavity and intestine but can become an opportunist microrganism and cause severe infections. A serie of 10 aminochalcones were designed and synthetized to obtain compounds anti-Candida with potent and broad-spectrum activity. The most active compound J34 demonstrated excellent in vitro activity against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida glabrata and Candida krusei with minimum inhibitory concentration between 1.

Cryptococci are intrinsically resistant to the latest generation of antifungals, echinocandins, while , a notorious global threat, is also increasingly resistant. We performed a natural product extract screen for rescue of the activity of the echinocandin caspofungin against H99, identifying butyrolactol A, which restores echinocandin efficacy against resistant fungal pathogens, including .

Surface-active agents are widely used in industrial processes and products for daily use. Surfactants are essential in consumer products, although they are environmentally harmful. Consequently, new technologies are being sought to address the surfactant waste problem effectively.

Background And Purpose: TMEM16A chloride channels constitute a depolarising mechanism in arterial smooth muscle cells (SMCs) and contractile cerebral pericytes. TMEM16A pharmacology is incompletely defined. We elucidated the mode of action and selectivity of a recently identified positive allosteric modulator of TMEM16A (PAM_16A) and of a range of TMEM16A inhibitors.
