Curr Pharm Des. 2024 Apr 29. doi: 10.2174/0113816128304018240415095912. Online ahead of print.ABSTRACTIn recent years, advancements in chemistry have allowed the tailoring of materials at the nanoscopic level as needed. There are mainly four main types of nanomaterials used as drug carriers:metal-based nanomaterials, organic nanomaterials, inorganic nanomaterials, and polymer nanomaterials. The nanomaterials as a drug carrier showed advantages for decreased side effects with a higher therapeutic index. The stability of the drug compounds is increased by encapsulation of the drug within the nano-drug carriers, leading to de...

Enhancing structural diversity of terpenoids by multisubstrate terpene synthases
Abstract
Terpenoids are one of the largest class of natural products with diverse structures and activities. This enormous diversity is embedded in enzymes called terpene synthases (TSs), which generate diverse terpene skeletons via sophisticated cyclization cascades. In addition to the many highly selective TSs, there are many promiscuous TSs that accept multiple prenyl substrates, or even noncanonical ones, with 6, 7, 8, 11, and 16 carbon atoms, synthesized via chemical approaches, C-methyltransferases, or engineered lepidopteran mevalonate pathways. The substrate promiscuity of TSs not only expands the structural divers...

Molecules, Vol. 29, Pages 2074: Enhanced Heterogeneous Fenton Degradation of Organic Dyes by Bimetallic Zirconia-Based Catalysts
niele Goi
The qualitative impact of pollutants on water quality is mainly related to their nature and their concentration, but in any case, they determine a strong impact on the involved ecosystems. In particular, refractory organic compounds represent a critical challenge, and several degradation processes have been studied and developed for their removal. Among them, heterogeneous Fenton treatment is a promising technology for wastewater and liquid waste remediation. Here, we have developed mono- and bimetallic formulations based on Co, Cu, Fe, and Mn, which were investigated for the degradation of three model organi...
