Abstract

4-benzoyl-5-phenyl-1-(4-(trifluoromethyl)phenyl)-1H-pyrazole-3-carboxylic
acid 2 was obtained from 4-benzoyl-5-phenyl-2,3-furandione 1 and (4-(trifluoromethyl)phenyl) benzaldehyde-phenyl hydrazone 1a. Obtained new pyrazole carboxylic
acid derivative was converted into acid chloride form. Reaction of new
derivatives between acid chloride and some of nucleophiles were progressed. The
esters (4a-c) were obtained using
Schotten Baumann method with the corresponding alcohols and acid chloride (3). Pyrazolopiridazinone derivatives (8, 9,
10) were obtained as a result of
cyclization reactions between pyrazole carboxylic acid and various hydrazines.
Additionally, reactions between an acide
chloride 3 and certain amines and
ureas were carried out to yield amides (5a,
5b-f) and carbo-urea (6a-c) derivatives. The nitrile compound
(7) was also synthesized from the
amine compound via the removal of water with the use of SOCl₂
and DMF. All synthesized molecules were subjected to antibacterial
activity to see their potential as unknown reagent. 6-nitro-3,4-diphenyl-2-(4-(trifluoromethyl)phenyl)-2,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one
(10) showed antibacterial activity
against only the Gram-positive bacteria, Bacillus cereus and Micrococcus luteus, with a
MIC value of 32 and 128 µg/mL, respectively. This finding revealed that
functional group is important for antibacterial activity. Compound 10 having a
nitro group inhibited growing of bacteria more than positive control,
streptomycin in two different types of bacteria. This might be a good clue for
further investigation about antibacterial agents.

Triflorometil Grubuna Sahip Pirazol-3-karboksilik Asit Sentezi ve Bazı Tepkimeleri

Abstract

4-Benzoil-5-fenil-2,3-furandion 1 ve (4-(triflorometil)fenil)
benzaldehit-fenil hidrazonun 1a
reaksiyonundan 4-benzoil-5-fenil-1-(4-(triflorometil)fenil)-1H-karboksilik
asit 2 elde edildi. Elde edilen yeni
pirazol karboksilik asit (2) türevi,
asit klorürüne dönüştürüldü ve çeşitli nükleofillerle asit klorür arasında yeni
türevlerin reaksiyonları gerçekleştirildi. Esterler (4a-c), ilgili alkoller ve asit klorür (3) ile Schotten Baumann metodu kullanılarak elde
edildi.  Pirazolopiridazinon türevleri (8, 9,
10), pirazol karboksilik asit ve
çeşitli hidrazinler arasındaki halkalanma reaksiyonları sonucunda elde edildi. Ek
olarak, amidleri (5a, 5b-5f) ve karbon-üre türevlerini (6a-c) elde etmek için asit klorür ile
çeşitli aminler ve ürelerle reaksiyonlar gerçekleştirildi. Nitril bileşiği (7), SOCl₂ ve DMF kullanılarak amin
bileşiğinden suyun uzaklaştırılması ile elde edildi. Sentezlenen
tüm moleküller, potansiyel aktivitelerinden dolayı antimikrobiyal aktiviteye
tabi tutuldu. Moleküllerden 6-nitro-3,4-difenil-2-(4-(triflorometil)fenil)-2,6-dihidro-7H-pirazolo[3,4-d]piridazin-7-on
bileşiğinin (10) sadece Gram-pozitif
bakterilere karşı antibakteriyal aktivite gösterdi. Bacillus cereus ve Micrococcus
luteus, A MIC değerleri 32 ve 128 µg/mL aktif olduğu bulundu. Yapısında
nitro grubu bulunduran ve aktivite gösteren 10 nolu molekülden dolayı
fonksiyonel grubun aktivite üzerinde önemli bir etkisi olduğu söylenebilir.
Ayrıca 10 nolu molekülün pozitif kontrol olan streptomycin antibiyotiğinden daha
etkili bir zon oluşturduğu da gözlendi. Bu durumda etkisini gösterdiği
bakteriler için ileri çalışmalar konusunda iyi bir antibiyotik adayı olabilir.
