    Description / Table of Contents: Zusammenfassung Von 20 Melanompatienten zeigen 85% eine überlange Persistenz eines deutlichen Erythems durch 8 MED mit 300 nm±10 nm (Kontrollgruppe nur 34%). Dieses Phänomen ist nicht mit den Hauttyp korreliert und kann zur prospektiven Identifizierung von Risikopatienten für Melanome und Lichtkarzinome (92%) Anwendung finden. Die Zahl spontaner und UV-C-induzierter „sister chromatid exchanges” (SCE) pro Metaphase ist in peripheren Leukozyten von Melanompatienten signifikant höher als bei der Kontrolle. Es wird der Versuch formuliert, ein „Risikospektrum” des Melanom-Phänotyps abzustecken.
    Notes: Summary Of 20 melanoma patients 85% show a prolonged erythema persistence after a marked test erythema of 8 MED with 300 nm±10 nm (control group only 34%). This phenomenon does not correlate with the skin type and is useful in identifying high-risk patients prone to melanoma and light-induced skin cancer (92%). The spontaneous and the UV-C-induced number of sister chromatid exchanges (SCE) per metaphase was significantly higher in peripheral leukocytes of melanoma patients than in normal controls. The attempt was made to establish a “risk-spectrum” of cutaneous melanoma phenotype.

    Description / Table of Contents: A One-step Synthesis of 2,4-Bis(secalkylamino)-6-halo-3-pyridinecarbonitrilesThe title compounds, e. g. 2a-c or 7, are obtained by reaction of malononitrile (1) with sec-alkyl halides/aluminium chloride (except the alkyl fluorides) at room temperature. From these the corresponding 2,4-bis(sec-alkylamino) pyridines may be conveniently prepared. With hydrogen bromide, 1 or its “dimer” 10 (R = H) 2,4-diamino-6-bromo-5-pyridinecarbonitrile (17) is formed.
    Notes: Malonsäuredinitril (1) liefert mit sec-Alkylhalogniden/Aluminiumchlorid (mit Ausnahme der Alkylfluoride) bei Raumtemperatur die Titelverbindungen (z. B. 2a-c Oder 7. Diese lassen sich glatt in die entsprechenden 2,4-Bis(sec-alkylamino)pyridine überführen. 1 oder das aus 2 Molekülen 1 gebildete 10b mit R = H geben mit Bromwasserstoff 2,4-Diamino-6-brom-5-pyridincarbonitril (17).
