Abstract

This study is an extention of our previous one which twelve 2— substitutedoxazolo (4,5-b) pyridine compound s were synthesized (1). In this research, the relation between the chemical structures and biological activities of these compound s were investigeted. T h e biological activity of all compound s were determined by Magnus method with guinea pig ileum in isolated organ bath. Th e mola r concentration of the compound s which inhibited the ileum cont - raction as 53 % induced by 0.1 histamine were determined. Partition coefficients were determined by using 1-octanol/water (Buffer Solution, pH : 7.8), R M values were determined by using 1-octanol (Stationary Phase), acetone/water (Buffer Solution, pH : 7.8). (30:70) (Mobil e Phase) as solvent systems. T h e quantitative relation between the biological activity and the physicochemical properties which were mentioned above were studied and the goo d correlations were obtained.

Özet

Bu çalışmada daha önc e sentezi yapılan 12 adetoksazolo (4,5-b) piridin türevinin (1), biyolojik etkileri saptanmış ve hidrofobik parametrelerle yapı ile etkileri arasında ilişki kurulmaya çalışılmıştır. Türevlerde, biyolojik etki olarak ele alınan antihistaminik etki şiddeti, Magnus tekniğine göre, 0.1 histaminin oluşturduğu kontraksiyonu inhibe eden mola r konsantrasyonların bulunması şeklinde saptanmıştır. 2-n-Hekziloksazolo (4,5-b) piridin türevi en etkili bileşik olarak bulunmuştur (1.3xl(10 - 7 mol/ml si, % 53 inhibisyonu sağlamaktadır). Bütün bileşiklerin dağılma katsayıları, 1-oktanol/su (Tampo n çözelti, pH : 7.8), R M değerleri ise; sabit faz 1-oktanol, hareketli faz aseton /su (Tampo n çözelti, pH : 7.8 ) (30/70) solvan sistemi kullanı- larak saptanmıştır. Bileşiklerin biyolojik etkileri ile dağılma katsayıları ve R değerleri kullanılarak yapı-etki ilişkileri incelendiğinde, biyolojik etki ile kullanılan bu fizikokimyasal parametreler arasında doğrusal bağıntı olduğu bulunmuştur.
