    Opis:
    In 1990, a new research group was constituted in the Institute of Chemistry, University of Wrocław. The team led by D.Sc. Lechosław Latos-Grażyński focused on the synthesis of novel macrocycles from the porphyrin family and their coordination abilities. The article describes the origins, development, and 30 years of activity of Porphyrin and Metalloporphyrin Chemistry Group.

    Opis:
    Heme oxygenase-1 (HO-1), an inducible enzyme degrading heme to biliverdin, iron and carbon monoxide, is involved in regulation of inflammation and angiogenesis. Tin protoporphyrin (SnPPIX) and zinc protoporphyrin (ZnPPIX) are commonly used as competitive inhibitors of HO-1. We aimed to compare the effects of SnPPIX and ZnPPIX on the production of vascular endothelial growth factor (VEGF), activity of inducible nitric oxide synthase (iNOS) and cell viability. All experiments were performed on rat vascular smooth muscle cells and murine RAW264.7 macrophages treated with 3-10 μM protoporphyrins. Some cells were additionally stimulated with IL-1β or with lipopolysaccharide. After a 24 h incubation period SnPPIX and ZnPPIX significantly reduced the generation of VEGF in vascular smooth muscle cells and RAW264.7, both in resting and stimulated cells. The inhibitory potentials of both protoporphyrins on VEGF synthesis were very similar. In contrast, analysis of iNOS activity revealed that results obtained with different HO-1 inhibitors are discrepant. Generation of nitric oxide by iNOS was significantly increased by SnPPIX but strongly decreased by ZnPPIX. Similar differences were observed when cell viability was compared. SnPPIX improved the cell survival rate, whereas the same doses of ZnPPIX exerted some cytotoxic effects. In summary, SnPPIX and ZnPPIX can be used as HO-1 inhibitors in some experimental models. However, these compounds produce also HO-independent effects, which can make the interpretation of experiments very uncertain. Thus the involvement of the HO-1 pathway should be always confirmed by more specific methods.

    Opis:
    The presented article describes the role of community of indigenous microorganisms occurring in the Kupferschiefer black shale in elements mobilization from fossil organic matter of the deposit. The short description of metalloorganic compounds and metalloporphyrins extracted from black shale was presented as well as the characterization of indigenous microorganisms. The processes of fossil organic matter colonization, biofilm development and elements mobilization accompanying bacterial growth was summarized.

    Opis:
    Optical chemical sensors enlarge the definition of a classical chemical sensor; they present results in two-dimensional (2D) or three-dimensional (3D) aspect. They can determine parameters of micro and macro scale objects without using a lot of electronic equipment. This article is focused on sensors based on porphyrin derivatives and europium complexes, being the most frequently used substances sensitive to oxygen concentration, pressure and temperature changes. Along with the presentation of characteristics of substances employed to sensors’ construction, also the general principle of luminescent sensors operation, composition and operation range of selected mono- and bifunctional luminescent sensors are described; moreover the selected achievements, such as the “traffic light” sensor are shown.
