The development of new chemical entities against the major diseases caused by parasites is highly desired. A library of thirty diamines analogs following a minimalist approach and supported by chemoinformatics tools have been prepared and evaluated agains
Photophysical properties of di-Schiff bases: Evaluating the synergistic effect of non-covalent interactions and alkyl spacers in enhanced emissions of solids
Das, Moyna,Baig, Fayaz,Sarkar, Madhushree
, p. 57780 - 57792 (2016/07/06)
Photophysical properties of di-Schiff base compounds in the solution and solid states are explored. The di-Schiff bases with alkyl spacers (ethyl, butyl and hexyl) showed enhanced light emitting properties in the solid state, while quenching was observed for di-Schiff bases with a hydrazine spacer. The photoluminescence spectra and the crystal structure were compared with bis-pyridyl-ethyl-di-imine and bis-pyridyl-butyl-di-imine. The crystal structure analysis of the compounds rationalizes the observed results. The concentration dependent 1H-NMR and NOESY spectra showed the aggregation behaviour of the compounds.

Observation of face-to-face host-guest associated states prior to threading of dialkylammonium ions into the DB24C8-like openings of a molecular cage

The threading of bis(dialkylammonium) ions through the DB24C8-like openings of a molecular cage proceeds through a stepwise mechanism: formation of a face-to-face complex between the NH2+ centers and the crown ether, significant diss

We achieved the synthesis of a derivative of phenylalanine with a diazamacrocycle on its side chain by macrocyclization of a dichloride on l-DOPA. We also report its incorporation into peptide structures by solid phase peptide synthesis which will lead to

A series of 25 N,N×-substituted diamines were prepared by controlled reductive amination of free aliphatic diamines with different substituted benzaldehydes. The library was screened in vitro for antiparasitic activity on the causative agents of human Afr
Design, synthesis and biological activity of peptidomimetic analogs of insect allatostatins
Xie, Yong,Kai, Zhen Peng,Tobe, Stephen S.,Deng, Xi Le,Ling, Yun,Wu, Xiao Qin,Huang, Juan,Zhang, Li,Yang, Xin Ling

Allatostatins (ASTs) comprise a family of insect neuropeptides isolated from cockroaches and found to inhibit the production of juvenile hormone (JH) by the corpora allata (CA). For this reason, the ASTs can be regarded as possible IGR candidates for pest control. Six peptidomimetic analogs according to the C-terminal pentapeptide of ASTs were prepared by solid-phase organic synthetic methods in an attempt to obtain new simple substitution agents. Assays of inhibition of JH biosynthesis in vitro by corpora allata from the cockroach Diploptera punctata showed that the activity of analog I (IC50: 0.09 μM) was more active than that of the C-terminal pentapeptide (Tyr-Xaa-Phe-Gly-Leu-NH2, IC50: 0.13 μM) it mimicked and the activity of the analog II (IC50: 0.13 μM) proved roughly equivalent to the C-terminal pentapeptide. The results indicate that a new simple mimicry for Tyr-Xaa-Phe-Gly has been discovered; analog I may be a novel compound candidate for potential IGRs. This study will be useful for the design of new AST analogs for insect management.

A total of 21 ferrocenyl and benzyl diaminoalcohols and diamines were synthesized and evaluated against Mycobacterium tuberculosis H37Rv. Interestingly, ferrocenyl diamines exhibit better activities than ferrocenyl diaminoalcohols.
Efficient synthesis of bolaform- and gemini-type alkyl-bis-[(α-amino)phosphonocarboxylic or phosphonic acid] surfactants
Vercruysse-Moreira, Karine,Déjugnat, Christophe,Etemad-Moghadam, Guita
, p. 5651 - 5658 (2007/10/03)
The synthesis of a new series of bolaform- and gemini-type phosphorus acid surfactants is described. The Pudovik addition reaction of P-H bond tetraoxyspirophosphoranes to symmetrical, prochiral bis-imines bearing different more or less long and rigid linkers occurs instantaneously at room temperature. This reaction is diastereoselective and quantitatively leads to the corresponding alkyl-bis-[α-aminospirophosphoranes] in good to high diastereomeric ratio. Selective and one-pot hydrolysis of these P*-C* bond bis-spirophosphoranes can be readily achieved either at room temperature by moist solvents giving the corresponding alkyl-bis-[α-aminophosphonocarboxylic acid] amphiphiles, or by a more drastic reaction of 20% aqueous hydrochloric acid under reflux affording free alkyl-bis-[α-aminophosphonic acid] surfactants in good yields.
