In recent years much effort has been carried out on formylations of amines. N-formyl compounds have been widely used in organic synthesis as protecting group of amines [1]. They are also used for synthesis of pharmaceutically important heterocylces [2-5]. Formamides are the Lewis bases, which are known to catalyze reactions such as allylations [6] and hydrosilylations [7] of carbonyl compounds....

The initiation of protein synthesis by Streptococcus faecalis R grown in folate-free culture occurs without N-formylation or N-acylation of methionyl-tRNA(f) (Met). Methionyl-tRNA synthetase and methionyl-tRNA formyltransferase were partially purified from S. faecalis grown under normal culture conditions in the presence of folate (plus-folate); the general properties of the enzymes were determ...

Lignin is a major waste product of biofuel and paper industries that can be used as modifier to improve the relevant properties asphalt. To investigate effect lignin formic acid wood incorporations into asphalt on binder was unaged aged for 85 min, 5 h, 10 series tests were conducted, including high- low-temperature rheological by dynamic shear rheometer (DSR), followed Fourier transform infrar...

Neutrophil infiltration of the lungs is associated with granuloma formation and severity tuberculosis infection. Although several cytokines chemokines are known to contribute lung neutrophil infiltration, neutrophilic chemotactic factors Mycobacterium ( Mtb ) remain unexplored. Therefore, we performed Transwell based assays using neutrophils from human peripheral blood mouse bone marrow probe a...
