Impacts of Steric Compression, Protonation, and Intramolecular Hydrogen Bonding on the N-15 NMR Spectroscopy of Norditerpenoid Alkaloids and Their Piperidine-Ring Analogues

H-1 -H-15 HMBC spectra of norditerpenoid alkaloids and their synthetic azabicyclic analogues were obtained to investigate the impacts of the through-space effect of steric compression, protonation, and formation of intramolecular hydrogen bonding on the N-15 NMR spectroscopy of these natural products and their piperidine-containing analogues. A rare N-15 NMR effect of steric compression is demonstrated in half-cage A/E-rings of norditerpenoid alkaloid free bases and their synthetic azabicyclic analogues, in which the distribution of the lone pair of electrons of the tertiary amine N-atom is sterically restricted by bridged cycloalkanes, e.g., cyclopentane, cyclohexane, and cycloheptane rings. This results in significant changes in the N-15 chemical shift, typically by at least similar to 10 ppm. The lone pair of electrons of the N-atom in the piperidine ring are sterically compressed whether the bridged cyclohexane ring adopts a chair or boat conformation. The( 15)N chemical shifts of 1 alpha-OMe norditerpenoid alkaloid free bases significantly increase (Delta delta(N) >= 15.6 ppm) on alkaloid protonation and thence the formation of an intramolecular hydrogen bond between N+-H and 1 alpha-OMe. The intramolecular hydrogen bonds between the N-atom and 1 alpha-OH of 1 alpha-OH norditerpenoid alkaloid free bases, karacoline, condelphine, and neoline stabilize their A-rings, adopting an unusual twisted-boat conformation, and they also significantly increase delta(N) of the tertiary amine N-atom.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 767-69-1 help many people in the next few years. Formula: C5H3BrN4.

Design of cationic amphiphiles for generating self-assembled soft nanostructures, micelles and hydrogels

Design of amphiphiles to develop robust self-assembled soft nanomaterials, such as micelles and hydrogels is an interesting subject. A series of cationic amphiphilic compounds were synthesized comprising 1-ethoxy (3-pentadecyl) benzene as the hydrophobic tail. The second carbon of ethoxy was linked to quaternary head groups (trimethyl ammonium bromide (PEA), triethyl ammonium bromide (PETE), pyridinium bromide (PEPy),N-methyl morpholino bromide (PENM),N-methyl piperidine bromide (PENP)). Inclusion of benzene ring leads to a significant decrease in critical micellar concentration (CMC) as compared to other cationic surfactants, such as cetyl trimethyl ammonium bromide (CTAB). Interestingly, at higher concentration, these cationic amphiphiles were forming soft hydrogels with critical gelation concentration (CGC) from 3 to 10% (w/v). The small-angle X-ray scattering (SAXS) analysis of xerogel revealed the formation of self-assembled lamellar patterns of molecules. Further, the morphology of xerogels were also seen under a scanning electron microscope (SEM) which correlates with SAXS data. The SAXS and SEM data confirms the formation of worm-like micellar structures and entangle themselves to form a hydrogel. The cytotoxicity assay was done on HDFA, HeLa and HEK cell lines, haemolysis assay showed better haemocompatibility than CTAB. The synthesized surfactants exhibited up to 3-fold higher solubilization capability against hydrophobic molecules than CTAB.

Synthesis, biological evaluation and QSAR studies of new thieno [2,3-d] pyrimidin-4(3H)-one derivatives as antimicrobial and antifungal agents

A series of new thieno [2,3-d]pyrimidin-4(3H)-one derivatives were synthesized and evaluated for their activity against four gram-positive and four gram-negative bacterial and eight fungal species. The majority of the compounds exhibited excellent antimicrobial and antifungal activity, being more potent than the control compounds. Compound 22, bearing a m-methoxyphenyl group and an ethylenediamine side chain anchored at C-2 of the thienopyrimidinone core, is the most potent antibacterial compound with broad antimicrobial activity with MIC values in the range of 0.05-0.13 mM, being 6 to 15 fold more potent than the controls, streptomycin and ampicillin. Furthermore, compounds 14 and 15 which bear a p-chlorophenyl and m-methoxyphenyl group, respectively, and share a 2-(2-mercaptoethoxy)ethan-1-ol side chain showed the best antifungal activity, being 10-15 times more potent than ketoconazole or bifonazole with MIC values 0.013-0.026 and 0.027 mM, respectively. Especially in the case of compound 15 the low MIC values were accompanied by excellent MFC values ranging from 0.056 to 0.058 mM. Evaluation of toxicity in vitro on HFL-1 human embryonic primary cells and in vivo in the nematode C. elegans revealed no toxic effects for both compounds 15 and 22 tested at the MIC concentrations. Ligand-based similarity search and molecular docking predicted that the antibacterial activity of analogue 22 is related to inhibition of the topoisomerase II DNA gyrase enzyme and the antifungal activity of compound 15 to CYP51 lanosteml demethylase enzyme. R-Group analysis as a means of computational structure activity relationship tool, highlighted the compounds’ crucial pharmacophore features and their impact on the antibacterial and antifungal activity. The presence of a N-methyl piperidine ring fused to the thienopyrimidinone core plays an important role in both activities.

Nucleophile-assisted cyclization of beta-propargylamino acrylic compounds catalyzed by gold(I): a rapid construction of multisubstituted tetrahydropyridines and their fused derivatives

Au(I)-catalyzed cyclization of beta-propargylamino acrylic derivatives 1, carried out in the presence of methanol, afforded tetrahydropyridines 3 in high isolated yields. An intramolecular version, using substrates with pending OH, NHBoc and 3-MeOC6H4 groups as internal O-, N-, and C-nucleophiles, yielded the orthofused cyclic derivatives, namely furo[2,3-b]pyridine derivative 14, pyrrolo[2,3-b]pyridine 18, and an unusual chromeno[3,4-c]pyridine 22 with a new quaternary carbon center. Synthetic utilization of the tetrahydropyridines 3 has been demonstrated by their conversion into substances with privileged pharmacophore scaffold. Thus, four 4-aryl piperidine derivatives 23a,b,f,g were obtained on catalytic hydrogenation of the representative 4-aryl tetrahydropyridines 3a,b,f,g; furthermore, the Diels-Alder cycloaddition of dimethyl acetylene dicarboxylate (DMAD) to dienes 3r-3u, possessing a masked dendralene framework, afforded tetrahydroisoquinolines 25r-25u that can be aromatized to produce polysubstituted isoquinolines, as demonstrated by the conversion of 25r into 27r. These domino transformations thus offer numerous variations of this methodology and reveal its potential for synthetic applications.
