Inhibitory effects of human salivary histatins and lysozyme on coaggregation between Porphyromonas gingivalis and Streptococcus mitis.
The effects of histatins on coaggregation between Porphyromonas gingivalis 381 and Streptococcus mitis ATCC 9811 were investigated by using a turbidimetric assay. The coaggregation activity was significantly inhibited by histatins 5 and 8 and strongly by lysozyme. Tritium-labeled histatin 8 bound to P. gingivalis cells but not to S. mitis cells.

OBJECTIVE Human saliva contains a family of low molecular weight histidine-rich proteins, named histatins, characterised by bactericidal and fungicidal activities in vitro against several microbial pathogens, such as Streptococcus mutans and Candida albicans. They represent a major component of an innate host non-immune defense system. In an earlier study we described the distribution of histat...

Chemotherapy continues to be the standard treatment for advanced or metastasized cancer. However, commonly used chemotherapeutic agents may induce damage in healthy cells and tissues. Thus, in recent years, there has been an increased focus on the development of new, efficient anticancer drugs exhibiting low toxicity and that are not affected by mechanisms of chemoresistance. In the present wor...

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولMembrane-induced helical conformation of an active candidacidal fragment of salivary histatins.
The conformational preference of the candidacidal C-terminal 16 residue fragment (9-24; G-Y-K-R-K-F-H-E-K-H-H-S-H-R-G-Y) of salivary histatin 5 was examined in water, methanol, and dimethyl sulfoxide solutions using 500 MHz two-dimensional-NMR. Fourier transform infrared and CD spectroscopy were used to delineate its membrane-bound conformation in lipid vesicles. The peptide backbone and side-c...
