Pyridine-type complexes of transition-metal halides XIV. Part III. Complexes with 2,4-, 2,6-, 3,4- and 3,5-lutidines

Compounds obtained by a solid-gas phase reactions between copper(II) chloride and bromide and 2,4-, 2,6-, 3,4- and 3,5-lutidines were studied using thermogravimetry, far-infrared, electronic spectroscopy and X-ray diffraction.

[Zn{SSi(OBut)3}2(NH3)]2 (1) reacts with 2-picoline or 2,4-lutidine (L) without elimination of ammonia giving stable monometallic complexes [Zn{SSi(OBut)3}2(NH3)L] (3 and 4), with two different nitrogen ligands bonded to the metal center. Reaction of (ButO)3SiSH with zinc di(acetylacetonate) in ammonia atmosphere leads to the complex with two ammine ligands [Zn{SSi(OBut)3}2(NH3)2] ¡¤ MeCN (5). Molecular and crystal structures of 3, 4 and 5 have been determined by the single crystal X-ray structural analysis. All have distorted tetrahedral geometry.

Current status and need for standards in ion mobility spectrometry

Ion mobility spectrometry (IMS) is a well established technique for the detection of many compounds of interest based on the reduced mobility (K0) values of their ions. While having the advantage of small size, weight, and power, IMS has been subject to low specificity and is subject to interferences that can cause false alarms in detectors used for security applications. The rate of false positive alarms is directly related to the detection window width required to maintain a high rate of true positive detections. These window widths are in turn a result of the historically available accuracy of reference measurements and the range of responses by multiple detectors. The windows cannot be arbitrarily reduced without risking an increase in the rate of false negative responses. Ongoing work has focused on high accuracy calibration as a means of decreasing the false alarm rates by reducing the variability between detectors which would allow for narrower detection windows. Central to the calibration procedure is the selection of an appropriate calibrant (or reference standard) that can be easily characterized and known with a high degree of certainty across a range of instrumental conditions. This review evaluates a number of previously proposed and potential calibrants against seven recommended criteria of suitability. We examine the sources of false positive alarms in IMS-based detectors and propose a calibration procedure based on high accuracy reference measurements. Initial results of applying this procedure in a post-processing manner are promising towards reducing detector variability and detection window width.

Alpelisib

Phosphatidylinositol 4,5-bisphosphate 3-kinases (PI3Ks) play a central role in numerous biological processes (such as cell death and proliferation, cell migration, energetic metabolism, etc.), which indicates that they have specific involvemen tin many oncogenic processes. PI3Ks frequently mutate, and most mutations lead to overactivation of the corresponding protein. Based on these observations, pharmaceutical companies have developed various P13K inhibitors: pan-PI3K, dualPI3K/mTOR pathway and P13K-specific inhibitors. There are three different subclasses of enzyme iso form for PI3Ks. The protein piiOa (PIK3CA) is in class I, and is the flagship memberof this family because of its very high mutation frequency in cancer. BYL-719 oralpelisib is an ATP-competitive pIIOa-specific inhibitor recently developed by Nova rtis and currently in clinical evaluation after positive preclinical investigations. The present paper is an overview of recent publications on progress made with PI3Ks, and how they are of interest in oncology, and on alpelisib and its clinical therapeutic prospects.

Group-contribution based estimation of pure component properties

A new method for the estimation of properties of pure organic compounds is presented. Estimation is performed at three levels. The primary level uses contributions from simple groups that allow describing a wide variety of organic compounds, while the higher levels involve polyfunctional and structural groups that provide more information about molecular fragments whose description through first-order groups is not possible. The presented method allows estimations of the following properties: normal boiling point, critical temperature, critical pressure, critical volume, standard enthalpy of formation, standard enthalpy of vaporization, standard Gibbs energy, normal melting point and standard enthalpy of fusion. The group-contribution tables have been developed from regression using a data set of more than 2000 compounds ranging from C = 3-60, including large and complex polycyclic compounds. Compared to the currently used group-contribution methods, the new method makes significant improvements both in accuracy and applicability.

Metabolic profiling of human blood by high-resolution ion mobility mass spectrometry (IM-MS)

A high-resolution ion mobility time-of-flight mass spectrometer with electrospray ionization source (ESI-IM-MS) was evaluated as an analytical method for rapid analysis of complex biological samples such as human blood metabolome. The hybrid instrument (IM-MS) provided an average ion mobility resolving power of ?90 and a mass resolution of ?1500 (at m/. z 100). A few muL of whole blood was extracted with methanol, centrifuged and infused into the IM-MS via an electrospray ionization source. Upon IM-MS profiling of the human blood metabolome approximately 1100 metabolite ions were detected and 300 isomeric metabolites separated in short analyses time (30. min). Estimated concentration of the metabolites ranged from the low micromolar to the low nanomolar level. Various classes of metabolites (amino acids, organic acids, fatty acids, carbohydrates, purines and pyrimidines, etc.) were found to form characteristic mobility-mass correlation curves (MMCCs) that aided in metabolite identification. Peaks corresponding to various sterol derivatives, estrogen derivatives, phosphocholines, prostaglandins, and cholesterol derivatives detected in the blood extract were found to occupy characteristic two-dimensional IM-MS space. Low abundance metabolite peaks that can be lost in MS random noise were resolved from noise peaks by differentiation in mobility space. In addition, the peak capacity of MS increased sixfold by coupling IMS prior to MS analysis.
