- Ferrostatins inhibit oxidative lipid damage and cell death in diverse disease models
-
Ferrostatin-1 (Fer-1) inhibits ferroptosis, a form of regulated, oxidative, nonapoptotic cell death. We found that Fer-1 inhibited cell death in cellular models of Huntington's disease (HD), periventricular leukomalacia (PVL), and kidney dysfunction; Fer-1 inhibited lipid peroxidation, but not mitochondrial reactive oxygen species formation or lysosomal membrane permeability. We developed a mechanistic model to explain the activity of Fer-1, which guided the development of ferrostatins with improved properties. These studies suggest numerous therapeutic uses for ferrostatins, and that lipid peroxidation mediates diverse disease phenotypes.

- Design, synthesis and antiviral activity of 2-(3-amino-4-piperazinylphenyl) chromone derivatives
-
Previously, we have confirmed that the antiviral activities of the chromone derivatives were controlled by the type as well as the position of the substituents attached to the chromone core structure. In the course of our ongoing efforts to optimize the antiviral activity of the chromone derivatives, we have been attempting to derivatize the chromone scaffold via introduction of various substituents. In this proof-of-concept study, we introduced a 3-amino-4-piperazinylphenyl functionality to the chromone scaffold and evaluated the antiviral activities of the resulting chromone derivatives. The synthesized 2-(3-amino-4-piperazinylphenyl)- chromones showed severe acute respiratory syndrome-corona virus (SARS-CoV)-specific antiviral activity. In particular, the 2-pyridinylpiperazinylphenyl substituents provided the resulting chromone derivatives with selective antiviral activity. Taken together, this result indicates the possible pharmacophoric role of the 2-pyridinylpiperazine functionality attached to the chromone scaffold, which warrants further in-depth structure-activity relationship study.

- Synthesis of nitrogen and sulfur analogues of the seco-CI alkylating agent
-
Two complementary syntheses of amino seco-CI (CI = 1a,2,3,5-tetrahydro-1H-cycloprop[1,2-c]indol-5-one) alkylating agents starting from isomeric chloronitrobenzoic acids are reported. Further reactions of these compounds, including diazotisation to phenol and thiophenol derivatives, and alkylation and acylation reactions relevant to the preparation of pro-drug forms are also described.

- 4-Substituted 1-chloro-2-nitrobenzenes: Structure-activity relationships and extension of the substrate model of rat glutathione S-transferase 4-4
-
In the present study, eleven 4-substituted 1-chloro-2-nitrobenzenes were tested for their GSH conjugation capacity when catalyzed by base or rat glutathione S-transferase (GST) 4-4. Kinetic parameters (k(s) and K(m), k(cat), and k(cat)/K(m)) were determined and subsequently used for the description of structure-activity relationships (SAR's). For this purpose, eight physicochemical parameters (electronic, steric, and lipophilic) of the substituents and five computer-calculated parameters of the substrates (charge distributions and several energy values) were used in regression analyses with the kinetic parameters. The obtained SAR's are compared with corresponding SAR's for the GSH conjugation of 2-substituted 1-chloro-4- nitrobenzenes, previously determined [Van der Aar et al. (1996) Chem. Res. Toxicol. 9, 527-534]. The kinetic parameters of the 4-substituted 1-chloro- 2-nitrobenzenes correlated well with the Hammett σ(p)- constant; the Hammett σ(p) constant corrected for 'through resonance', while the corresponding kinetic parameters of the 2-substituted 1-chloro-4- nitrobenzenes did not. The base-and GST 4-4-catalyzed GSH conjugation reactions of 2-substituted 1-chloro-4-nitrobenzenes depend to a different extent on the electronic properties of the ortho substituents, suggesting the involvement of different rate-limiting transition states. The base- and GST 4-4-catalyzed conjugation of 4-substituted 1-chloro-2-nitrobenzenes, however, showed a similar dependence on the electronic properties of the para substituents, indicating that these substrates are conjugated to GSH via a similar transition state. Multiple regression analyses revealed that, besides electronic interactions, also steric and lipophilic restrictions appeared to play an important role in the GST 4-4-catalyzed GSH conjugation of 4- substituted 1-chloro-2-nitrobenzenes. Finally, the 4-substituted 1-chloro-2- nitrobenzenes were also used to extend the previously described substrate model for GST 4-4 [De Groot et al. (1995) Chem. Res. Toxicol. 8, 649-658], by which a specific steric restriction of substrates for GST 4-4 became clear.

- Nitrogen and sulfur analogues of the seco-CI alkylating agent: Synthesis and cytotoxicity
-
The first synthesis of seco-CI alkylating agents bearing a nitrogen or sulfur substituent in place of the oxygen at C-6 is described. In comparison with a phenol, an amino substituent confers reduced but significant cytotoxicity, even when mono- or dimethylated, while sulfur analogues are considerably less potent.
