“…Sample flow is split isokinetically into a main flow passing through the filter and a bypass flow each controlled by a mass flow controller (Lim et al 2003 andKosch et al 2005). (Lim et al, 2003) A multi-point dust sampler has been developed by Wang et al (2000) and Wang et al (1999a) to measure the spatial dust distribution at different ventilation rates in a mechanically ventilated airspace using an array of critical venturi orifices for controlling the airflow rate at each sampling point, figure (2). It consists of a commercially available vacuum pump, a pressure monitor, a pressure regulator, an array of filter holders, filters, critical venturi orifices and sampling heads.…”

Heterocyclic chalcones have been prominent in the scientific community due to various biological activities reported for these compounds. The structural knowledge of heterocyclic chalcones can help in the understanding of their mechanism of action. The Hirshfeld surfaces were used to study the supramolecular arrangement of two conformers present into asymmetric unit of the heterocyclic chalcone (2E)-3-(4-methylphenyl)-1-(pyridin-3-yl)-prop-2-en-1-one on crystalline state. In addition, the linear polarizability (α), the first hyperpolarizability (β||z), and the second hyperpolarizability (γ) of the conformers were calculated to get a better insight on the linear and nonlinear optical behaviors of these structures in presence of solvent medium, as well as their band-gap energies. The Hirshfeld surfaces confirmed the presence of C−H···N, C−H···O and C−H···C interactions in packaging stabilization. Finally, the 2D fingeprint plot was used to the quantification of contacts and indicated that there are both π···π and C−H···π interactions present in the compound.

The Complement inhibitor K-76 was isolated from the supernatant of the culture broth of the fungus Stachybotrys complementi, nov. sp. K-76. The natural product is a sesquiterpenic dialdehyde which can be partially oxidized to the monocarboxylic acid derivative (K-76 COOH, MX-1), the sodium salt of which is more soluble and less toxic than the natural product. Both, K-76 and K-76 COOH inhibit Complement activation by the classical and alternative pathways, mainly at the C5 level. Reviewed here are the isolation and total syntheses of the natural product as well as aspects of its Complement inhibitory activity. Approaches to the synthesis of grisan, which bears the BCD skeleton of the natural product, as well as the synthesis of CD-, BCD-and ACD-ring structural analogues of K-76, including the use of natural products as starting materials, and evaluation of their biological activity as Complement inhibitors, are also discussed.
