Sulfonamides with Heterocyclic Periphery as Antiviral Agents

open access: yesMolecules, 2022
Sulfonamides are the basic motifs for a whole generation of drugs from a large group of antibiotics. Currently, research in the field of the new sulfonamide synthesis has received a “second wind”, due to the increase in the synthetic capabilities of ...

Crystal structure and Hirshfeld surface analysis of N-(4-nitrophenyl)-2-(piperidin-1-yl)acetamide (lidocaine analogue)

open access: yesActa Crystallographica Section E: Crystallographic Communications
In the title molecule, C13H17N3O3, the substituents on the phenyl ring are rotated slightly out of the mean plane of the ring but the piperidine moiety is nearly perpendicular to that plane. In the crystal, C—H...O hydrogen bonds form chains of molecules

Piperidine-1-carboximidamide [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2012
In the title compound, C(6)H(13)N(3), the C=N and C-N bond lengths in the CN(3) unit are 1.3090 (17), and 1.3640 (17) (C-NH(2)) and 1.3773 (16) Å, indicating double- and single-bond character, respectively. The N-C-N angles are 116.82 (12), 119.08 (11) and 124.09 (11)°, showing a deviation of the CN(3) plane from an ideal trigonal-planar geometry.

Network-analysis-guided synthesis of weisaconitine D and liljestrandinine. [PDF]

open access: yes, 2015
General strategies for the chemical synthesis of organic compounds, especially of architecturally complex natural products, are not easily identified. Here we present a method to establish a strategy for such syntheses, which uses network analysis.

Next‐Generation Bio‐Reducible Lipids Enable Enhanced Vaccine Efficacy in Malaria and Primate Models

open access: yesAdvanced Functional Materials, EarlyView.
Structure–activity relationship (SAR) optimization of bio‐reducible ionizable lipids enables the development of highly effective lipid nanoparticle (LNP) mRNA vaccines. Lead LNPs show superior tolerability and antibody responses in rodents and primates, outperforming approved COVID‐19 vaccine lipids.

An Efficient Synthesis of Aldohexose-Derived Piperidine Nitrones: Precursors of Piperidine Iminosugars

open access: yesMolecules, 2013
D-Glucopyranose-derived and L-idopyranose-derived piperidine nitrones were synthesized in good overall yields through six-step reaction sequence starting from readily available 2,3,4,6-tetra-O-benzyl-D-glucopyranose.

Total synthesis of (±)-paroxetine by diastereoconvergent cobalt-catalysed arylation

open access: yes, 2014
A total synthesis of paroxetine is reported, with a diastereoselective and diastereoconvergent cobalt-catalysed sp3–sp2 coupling reaction involving a 3-substituted 4-bromo-N-Boc-piperidine (Boc = tert-butoxycarbonyl) substrate as a key step.

Tetrahydropyrazolo[1,5-a]Pyrimidine-3-Carboxamide and N-Benzyl-6′,7′-Dihydrospiro[Piperidine-4,4′-Thieno[3,2-c]Pyran] analogues with bactericidal efficacy against Mycobacterium tuberculosis targeting MmpL3 [PDF]

open access: yes, 2013
Mycobacterium tuberculosis is a major human pathogen and the causative agent for the pulmonary disease, tuberculosis (TB). Current treatment programs to combat TB are under threat due to the emergence of multi-drug and extensively-drug resistant TB.
