A series of 1-acyl-4-phenyl/(acridin-9-yl)thiosemicarbazides 3, including four new compounds, were prepared in order to study substituent effects on cyclization reactions with oxalyl chloride (producing imidazolidine-4,5-diones 4), dimethyl acetylenedicarboxylate (to give thiazolidin-4-ones 7 and 8) and autocondensation under alkaline conditions (to yield 1,2,4-triazoles 9). A positional isomer...

A novel potentiometric sensor based on ionophore (Cd(NH2CH2CH2OCH2CH2OCH2CH2NH2)Ag3(CN)5) for the determination of β-N-oxalyl-L-α, β-diaminopropionic acid (ODAP) is developed. The ODAP-selective membrane sensor demonstrates high sensitivity and short response time. The detection limit of the ODAP-selective membrane sensor is about 2 × 10(-6) mol L (-1) and the response time is shorter than 6 s....

Mammalian neurolathyrism is a progressive and degenerative disease of central nervous system originating from excessive consumption of Lafhyrus seeds, particularly those of L. sativus. Rao et al. [I] have isolated P-N-oxalyl-L-a&diaminopropionic acid (ODAP) from the seeds of L. satiuus and shown this substance to be the neurotoxin [ 1, 21 Characterization of the biochemical effect and cellular ...

Baklagiller familyasında yer alan mürdümük (Lathyrus sativus L.) hayvan besleme açısından oldukça önemli bir yere sahiptir. Bitki kuraklığa toleranslı olup, çok farklı topraklarda rahatlıkla gelişme gösterebilmektedir. Bu araştırma, Bilecik ekolojik koşullarında 4 adet tescilli çeşit (Gap Mavisi, Eren, İptaş ve Karadağ) 9 Türkiye orjinli yerel populasyon (1603, 2006, 2401, 4301, 4403, 5001, 640...

Chiral oxazoline based bi and hexadentate ligands built on cyclophosphazene cores have been synthesized and characterized. (NPPh2)2[NP(m-OC6H4C(O)OCH3)2] (1) was prepared by the reaction of gem-(NPPh2)2(NPCl2) with methyl-3-hydroxy benzoate in the presence of Cs2CO3. Compound 1 was converted to the dicarboxylic acid (NPPh2)2[NP(m-OC6H4C(O)OH)2] (2) by base promoted hydrolysis with KO(t-Bu). The...
