Cyclodextrin-based catalysts and molecular reactors [PDF]

open access: yes, 2015
We suggest two nonparametric approaches, based on kernel methods and orthogonal series to estimating regression functions in the presence of instrumental variables. For the first time in this class of problems, we derive optimal convergence rates, and

Psychedelics, entactogens and psychoplastogens for depression and related disorders

open access: yesBritish Journal of Pharmacology, EarlyView.
Currently, the most actively investigated rapidly acting antidepressants, anxiolytics and/or anti PTSD agents, include psychedelics e.g. psilocybin, LSD, N,N‐dimethyltryptamine, ayahuasca; non‐hallucinogenic entactogens, e.g. MDMA; psychoplastogens which rapidly promote neuroplasticity, e.g.

Topiramate for the treatment of neonatal seizures and beyond

open access: yesEpilepsia, EarlyView.
Abstract Acute symptomatic neonatal seizures are one of the most common neurological disorders in newborns admitted to neonatal intensive care units and require prompt treatment. Up to 50% of neonatal seizures are refractory to first‐line medications such as phenobarbital (PB), and another 30% fail second‐line therapy.

An Intramolecular Wittig Approach toward Heteroarenes: Synthesis of Pyrazoles, Isoxazoles, and Chromenone-oximes.

open access: yesOrganic Letters, 2019
α-Halohydrazones/ketoximes are transformed into trisubstituted pyrazoles/disubstituted isoxazoles by treatment with phosphine, acyl chloride, and a base.

Iterative approach to computational enzyme design [PDF]

open access: yes, 2012
A general approach for the computational design of enzymes to catalyze arbitrary reactions is a goal at the forefront of the field of protein design. Recently, computationally designed enzymes have been produced for three chemical reactions through the ...

Tautomerism, Conformational Analysis, and Intramolecular Interactions in Triketone–Chalcogenazole Hybrids

open access: yesJournal of Physical Organic Chemistry, Volume 38, Issue 11, November 2025.
Triketone herbicides inhibit HPPD via induced fit influenced by noncovalent interactions. Using DFT‐B3LYP and NBO analysis, this study examined hydrogen and chalcogen bonds in tautomer stabilization. Results showed enolic forms with stronger intramolecular interactions, while heavier atoms like sulfur and selenium uniquely facilitated chalcogen bonds ...

Catalyst Control in Positional-Selective C-H Alkenylation of Isoxazoles and a Ruthenium-Mediated Assembly of Trisubstituted Pyrroles.

open access: yesOrganic Letters, 2019
High levels of catalyst control are demonstrated in determining the positional selectivity in C-H alkenylation of isoxazoles. A cationic rhodium-mediated, strong-directing group promotes C( sp2)-H activation at the proximal aryl ring whereas, the ...

A Two-Step Synthesis of Unprotected 3-Aminoindoles via Post Functionalization with Nitrostyrene

open access: yesMolecules, 2023
A novel, low-cost method for the preparation of not easily accessible free 3-aminoindoles has been developed. This approach is based on a well-established reaction between indoles and nitrostyrene in the presence of phosphorous acid, which results in the
