Aryl phosphate derivatives of 3'-deoxythymidine (3dT), albeit more active than 3dT in thymidine kinase (TK)-deficient cells, are not potent anti-human immunodeficiency virus (HIV) agents and are capable of inhibiting HIV replication only at micromolar concentrations.

Psoriasis is a prevalent, chronic inflammatory disease characterized by abnormal skin plaques. To date, physical therapy, topical therapy, systemic therapy and biologic drugs are the most commonly employed strategies for treating psoriasis. Recently, many agents have advanced to clinical trials, and some anti-psoriasis drugs have been approved, including antibody drugs and small-molecule drugs.

Functionally derivatized analogs of prenyl lipids are valuable tools for the detection and analysis of prenylated proteins. Using a biotinylated analog of geranylgeranyl, we previously identified Ykt6 as a substrate for a novel protein prenyltransferase, termed geranylgeranyltransferase type III (GGTase-III). Ykt6 is an evolutionarily highly conserved SNARE protein that regulates multiple intracellular trafficking pathways, including intra-Golgi trafficking and autophagosome-lysosome fusion.

Organophosphate flame retardants (OPFRs) are a class of substances that pose potential risks to human health and ecosystems due to their large-scale production, wide range of applications, and ubiquitous presence in the environment. With their potential for long-range atmospheric transport (LRAT), OPFR pollution in high-altitude areas has become an increasing concern. Herein, a general pretreatment method for OPFRs across various sample matrices was established and combined with gas chromatography-mass spectrometry (GC-MS), utilizing a programmed temperature ramp in the vaporization chamber to enable high-throughput detection of OPFRs in various environmental matrices.

Article Synopsis
- Terpenoid cyclases (TCs) are crucial for producing diverse natural compounds, with the BcABA3 enzyme from the fungus Botrytis cinerea representing a unique type that deviates from typical TCs.
- Crystal structures of BcABA3 and related enzymes show they have an all-α-helix fold and interact with specific substrates through a unique binding mechanism.
- Findings suggest significant potential for exploring more uncharacterized terpenoids synthesized by these enzymes, highlighting the need for further research in this area.
Chemoenzymatic Formation of Oxa-Terpenoids by Sesqui- and Diterpene Synthase-Mediated Biotransformations with 9-Oxy-FPP Ether Derivatives.

Farnesyl pyrophosphate derivatives bearing an additional oxygen atom at position 5 proved to be very suitable for expanding the substrate promiscuity of sesquiterpene synthases (STSs) and the formation of new oxygenated terpenoids. Insertion of an oxygen atom in position 9, however, caused larger restraints that led to restricted acceptance by STSs. In order to reduce some of the proposed restrictions, two FPP-ether derivatives with altered substitution pattern around the terminal olefinic double bond were designed.
