AI Article Synopsis

  • Two series of pyrrole derivatives were synthesized and tested for their ability to inhibit the enzyme tyrosinase, which is important in melanin production.
  • Among the compounds, A12 showed the strongest inhibitory effect, being approximately 30 times more effective than the standard inhibitor, kojic acid.
  • The study found that A12 acts as a reversible and mixed-type inhibitor and effectively reduced tyrosinase activity in B16 melanoma cells, suggesting potential for further development as a lead compound for new inhibitors.

Article Abstract

In order to find potential inhibitors of tyrosinase, two series of pyrrole derivatives A (1-17) and B (1-8) were synthesized and screened for their inhibitory activities on tyrosinase. Most of the 2-cyanopyrrole derivatives exhibited effective inhibitory activities. In particular, A12 exhibited the strongest inhibitory activities, with the IC values of 0.97 μM, which is ∼30 times stronger than the reference inhibitor kojic acid (IC: 28.72 μM). The inhibitory mechanism analysis results revealed that A12 was a reversible and mixed-type inhibitor. Molecular docking experiments clarified the interaction between A12 with tyrosinase. Furthermore, A12 (100 μM) presented effective inhibitory effect on tyrosinase in B16 melanoma cells with inhibition of 33.48%, which was equivalent to that of Kojic acid (39.81%). Accordingly, compound A12 may serve as the lead structure for the further design of potent tyrosinase inhibitors. Molecular docking studies confirmed the interaction between the compound and tyrosinase.

Background: Glia mediated neuroinflammation and degeneration of inhibitory GABAergic interneurons are some of the hall marks of pyrethroid neurotoxicity. Here we investigated the sex specific responses of inflammatory cytokines, microglia, astrocyte and parvalbumin positive inhibitory GABAergic interneurons to λ-cyhalothrin (LCT) exposures in rats.

Methods: Equal numbers of male and female rats were given oral corn oil, 2 mg/kg.

Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.

The current study was designed to evaluate the antibacterial, antibiofilm, and biofilm inhibitory potential of six medicinal plants, including Trachyspermum ammi, Trigonella foenum-graecum, Nigella sativa, Thymus vulgaris, Terminalia arjuna, and Ipomoea carneaid against catheter-associated bacteria (CAB). Eighteen CAB were identified up to species level using 16S rRNA gene sequencing, viz., Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa.

Oxidative stress arises from an imbalance between reactive species (RS) production and the antioxidant defense, increasing the brain susceptibility to neurodegenerative and psychiatric diseases. Besides, changes in the expression or activity of neurotransmitter metabolism enzymes, such as monoamine oxidases (MAO), are also associated with mental disorders, including depression. Considering this, antioxidant and MAO-A activity inhibitory potential of six 2,3-chalcogenodihydrobenzofurans (2,3-DHBF) was investigated through in vitro and in silico tests.

Tumors are diseases caused by abnormal cell division and growth, which can be life-threatening if not treated properly. Serpin inhibitors play a crucial role in regulating pathophysiological process and are promising drug targets. Kallistatin (SERPINA4) and Pigment Epithelium-Derived Factor (PEDF, SERPINF1) are two serpins that lack protease inhibitory activity but are abundant in blood.
