    ABSTRACT: Synthetic procedures towards homodithiacalix[n]arenes are developed, starting from simple and readily available bifunctional aryl building blocks, by a dynamic covalent chemistry approach. Reaction of 1,3-bis(mercaptomethyl)-5-tert-butyl-2-methoxybenzene under basic conditions leads to a mixture of trimeric, tetrameric and pentameric dimethylenedithia-bridged cyclooligomers, whereas reaction of 5-tert-butyl-2-methoxy-1,3-bis(thiocyanatomethyl) benzene under reducing conditions (and subsequent oxidation) affords the homodithiacalix[4]arene macrocycle in a very selective fashion through efficient disulphide exchange chemistry.

    ABSTRACT: The in situ cryocrystallisation technique has been used to obtain four adducts between hexamethylphosphortriamide and 1,2-dihalotetrafluoroethanes having iodine, bromine and chlorine as halogen-bonding donor atoms. These systems allowed for a precise comparison of different C–X…O synthons. The effectiveness and reliability of the pharmacologically important C–Cl…O synthons are proven.

    ABSTRACT: The ionophoric activity of a calix[4]arene guanidinium conjugate (4G4Oct) has been investigated in bulk chloroform membrane and mainly in liposomes. In both membrane models 4G4Oct shows high activity in the transport of chloride. The mechanistic evidence suggests a carrier mechanism in which the calixarene binds the anions through electrostatic interactions and hydrogen bonds with the guanidinium moieties. Studies on anion transport in liposomes indicate a peculiar selectivity sequence inverse to the most commonly observed lyotropic series with chloride transported faster than bromide and iodide virtually non-transported. This selectivity sequence together with competitive inhibition of chloride transport by the non-transported ions suggests a strong anion binding to the guanidinium moieties in the membrane environment. The complex formed is lipophilic and is able to shuttle the ion across the membrane. The origin of the observed anion selectivity is suggested to be related to a less favourable ion exchange at the membrane interface of iodide with respect to chloride with OH-, which is the antiported ion in the transport process in liposome. These studies complement the reported ability of 4G4Oct to condensate plasmid DNA and to transfect cells, showing that the calixarene derivative is also able to efficiently transport chloride across a phospholipid bilayer.

    ABSTRACT: The association of 2,6-bis(cycloalkylcarbonylamino)pyridines with rigid and non-rigid counterparts in chloroform solution was studied using 1H NMR and computational methods. The angles within the cycloalkyl ring and the rotation of these substituents determine the strength of the association via triple hydrogen bonding. The dimerisation and methyl–methyl repulsion have been addressed as mechanisms restricting heterocomplexation of diacetamide. The association constants obtained by the shift changes of hydrogen-bonded protons are in agreement with those of methine protons. This ‘dual shift’ method was proposed as an additional verification of association constants obtained generally by amino protons.

    ABSTRACT: The commercial sunscreen agent Tinosorb S (TS) is a promising oil-soluble broad spectrum UV filter. Here, we report for the first time a water-dispersible inclusion complex of TS using cucurbituril. The synthesis was carried out via a supramolecular approach in the solid state by using the high-speed vibration milling technique. The formation and the photophysical properties of the solid inclusion complex were investigated by spectroscopic techniques such as UV–vis spectrophotometry, Fourier-transform infrared and solid-state proton nuclear magnetic resonance spectroscopy as well as by thermal gravimetric analysis and X-ray diffractometry. An increase in the absorbance and a shift of the maximum absorption from 380 nm to 345 nm for the inclusion complex were observed in comparison to the precursor complex TS. The stochiometric ratio of cucurbituril and TS in the inclusion complex was found to be 2:1

    ABSTRACT: Using the recommended modifications to isothermal titration calorimetry (ITC) analysis proposed by Turnbull and Daranas (J. Am. Chem. Soc. 2003, 125 14859-14866) and Tellinghuisen (Anal. Biochem. 2008, 373, 395-397), we determine the thermodynamic data for the binding of a series of halogenated guests to deep-cavity cavitand 1. These modifications allowed the accurate determination of the thermodynamic data of systems with c values of between 0.2 and 5; values that are much lower than is often suggested as the lower limit of ITC. The compiled data allowed a more accurate glimpse of the strength of the unusual C-H...X-R hydrogen bonds observed between these hosts and halogenated guests.

    ABSTRACT: Protonation constants for 3,6,9,16,19,22-hexaazatricyclo[22.2.2.2(11,14)]triaconta-1(27),11(30),12,14(29),24(28), 25-hexaene (P2) and 3,7,11,18,22,26-hexaazatricyclo[26.2.2.2(13,16)]tetratriaconta-1(31),13(34),14,16(33),28(32),29-hexaene (P3) and their host-guest interactions with tripolyphosphate (Tr) and ATP (At) have been determined and evaluated by H-1 NMR and potentiometric equilibrium methods. Ternary complexes were formed in aqueous solution as a result of hydrogen bond formation and Coulombic interactions between the host and the guest. For the case of ATP pi-stacking interactions were found. Formation constants for all the species obtained are reported and compared with the isomeric 3,7,11,19,23, 27-hexaazatricyclo[27.3.1.1(13,17)]tetratriaconta-1(33),13,15,17(34),29,31-hexaene (Bn) and 3,6,9,17,20,23-hexaazatricyclo[23.3.1.1(11,15)]triaconta-1(29),11,13,15(30), 25(27)-hexaene (Bd) ligands. Bonding interactions reach a maximum for H(6)P2Tr(+), yielding a logK(6)(R) value of 12.02. The selectivity of the P3 and P2 ligands with regard to ATP and Tr substrates (S) is discussed and illustrated with global species distribution diagrams showing a strong preference for the latter over the former as a consequence of the much stronger formation constants with Tr. An analysis of the isomeric effect was also carried out by comparing the P3-S vs. Bn-S and P2-S vs. Bd-S systems. For the systems using Tr, a selectivity of more than 97% (pH 5.0) was achieved for its complexation when using the meta (Bd) rather than the para (P2) isomer, due solely to the size and shape of the receptor's cavity. In the case of the P3 and Bn ligands the selectivity toward Tr complexation decreased to 85% (pH 8.0).
