In present study we reported the synthesis of benzoyl and sulphonyl
derivatives by taking Piperidine-4-carboxamide as principal molecule.
Both 33DDS and 44DDS isomers have the same electron withdrawing sulphonyl
group, where the only difference comes from the orientation of the N[H.sub.2] groups.
Biguanide and Sulphonyl
urea were the most commonly prescribed OADs.
Thirty experimental animals were fasted for 12 h and grouped as follows: group 1 (control), treated with isotonic saline solution (ISS, 4 mL/kg); group 2, treated with the fat fraction (16 mg/kg); group 3, treated with the protein fraction (16 mg/kg); group 4, treated with the chitin fraction (16 mg/kg); and group 5, positive control, treated with glibenclamide (10 mg/kg), a sulphonyl
urea agent with hypoglycemic action that acts at the pancreatic level as an insulin secretagogue.

urea herbicides on alkaline soil.
It binds to 65 kD protein on [beta]-cells, which appears to be a part of the same sulphonyl
urea receptor that binds Glibenclamide.
Briefly, mice kidneys were homogenized at 10% (w/v) in a Potter Elvehjem homogenizer (Wheaton, NJ, USA) using a homogenization buffer containing 20 mM HEPES, pH 7.9, 1mM Mg[Cl.sub.2], 0.5 mM EDTA, 1mM EGTA, 1mM dithiothreitol (DTT), 0.5 mM phenylmethyl sulphonyl
fluoride (PMSF), and 1 ul/ml PIC.
It is sulphonyl
urea group type of herbicide, and is composed of 10.1% metsulfuron methyl, 10.1% chlorimuron ethyl and remaining 79.80% adjuvants .
In other sets of experiments, the stimulated RAW 264.7 cells were washed with phosphate buffer solution (PBS, 137 mM NaCl, 2.7 mM KC1, 2 mM K[H.sub.2]P[O.sub.4], 10 mM [Na.sub.2]HP[O.sub.4], pH 7.4) and lysed in an ice cold radio immunoprecipitation assay (RIPA) buffer (TrisHC1, pH 7.2, 25mM;0.1% sodium dodecyl sulphate (SDS); EDTA; 1% Triton X-100; 1% sodium deoxycholate; 0.15 M NaCl) containing 1 mM phenylmethyl sulphonyl
fluoride (PMSF), 10 [micro]g/ml aprotinin, 1 mM sodium orthovanadate, and 5 [micro]g/ml leupeptin.
This observation suggests that coordination of metal with ligand does not occur through sulphonyl
