- Process for fluorinating inorganic or organic compounds by direct fluorination
-
The invention relates to the use of a fluorinated gas, wherein the elemental fluorine (F2) is present at a high concentration, the present invention relates to a process for producing fluorinated compounds by direct fluorination using a fluorination gas in which elemental fluorine (F2) is present at a high concentration, such as a concentration of elemental fluorine (F2), in particular equal to much higher than 15 vol% or even 20 vol% (i.e., at least 15 vol% or even 20 vol%), and to a process for producing fluorinated compounds by direct fluorination using a fluorination gas. The process of the present invention relates to the manufacture of fluorinated compounds other than fluorinated benzene by direct fluorination, in particular to the preparation of fluorinated organic compounds, end products and intermediates for use in agricultural, pharmaceutical, electronic, catalyst, solvent and other functional chemical applications. The fluorination process of the invention can be carried outin batches or in a continuous manner. If the process of the invention is carried out in batches, a column (tower) reactor may be used. If the process of the invention is continuous, a microreactor may be used.

- Pyrazole derivatives
-
The present invention relates to cis- and trans-forms of pyrazole derivatives, salts thereof, or agents containing the same, and represented by the general formula (I): wherein G represents a nitrogen containing saturated heterocyclic structure represented by the following formula: These compounds exhibit anti-tumor activity on 5-FU-resistant tumors and effects on P glycoprotein expressing, multiple-drug resistant tumors. An example of a pyrazole derivative which demonstrates 50% inhibition of tumor cell growth is 3-[4-(3-chloro-5-fluorophenyl)-1 piperazinyl]-1-[1-(3-chloro-2-pyridyl)-5-methyl-4-pyrazolyl)-1-trans-propene hydrochloride. Synthesis of the compounds represented by formula (I) can be prepared by any one of various routes such as a Mannich reaction, a Wittig reaction, reductive amination or substitution by allylation.

- Directed biosynthesis of 5'-fluoropactamycin in Streptomyces pactum
-
A new pactamycin analogue, 5'-fluoropactamycin, was prepared by directed biosynthesis. Supplementation of the fermentation medium of Streptomyces pactum, var. pactum with 3-amino-5-fluorobenzoic acid, an analogue of 3-aminobenzoic acid, an advanced precursor in pactamycin biosynthesis, resulted in co-production of pactamycin and the new pactamycin analogue. A similar feeding experiment with 3-amino-5-methylbenzoic acid did not result in formation of the corresponding methylated pactamycin analogue, but only in inhibition of pactamycin production. Comparison of antimicrobial and cytotoxic activities of pactamycin and 5'-fluoropactamycin showed no significant differences.
