Summary: We have synthesized pyrazole-carboxamides compounds; N [(1E)-(1,5-dimethyl-3-oxo- 2-phenyl-2,3-dihydro-1H-pyrazol-4-yl) methylene]-2-(6-methoxy)-2-naphthyl)-propionyl hydrazide (4), N-[(1E)-(1,3-diphenyl-1H-pyrazol-4-yl)methylene]-2-(6-methoxy-2-naphthyl) propionyl hydrazide (5), 2-(6-Methoxy-naphthalen-2-yl)-1-(3-phenyl-pyrazol-1-yl)propan-1-one (6), 2-(6- Methoxy-naphthalen-2-yl) -1-(5-phenyl-2,3-dihydro-pyrazol-1-yl)propan-1-one (7) and 2-(6- methoxynaphthalen-2-yl)-N-{4-[3-(4-methoxyphenyl)-acryloyl)]-phenyl}-propionamide (8) then characterized by IR, 1 H-NMR and 13 C-NMR techniques.
To the solution of substituted-1, 3benzothiazole-2-amines (1a-d, 0.1 mol) in DMF, propionyl chloride (0.2 mol) was added slowly with continuous stirring.

Acetylcarnitine- 4.16 (normal 8-150 [micro]mol/L), Octadecanoyl carnitine- 0.16 (normal 0.6-3.5 [micro]mol/L), Propionyl carnitine, Butyryl carnitine, Isovaleryl carnitine, Glutaryl carnitine were normal.
The most important and well-known pathway for fatty acid oxidation is [beta]-oxidation, in which fatty acids are converted into acetyl Co-A or propionyl Co-A (derived from odd-numbered fatty acid chains), and finally those Co-As are oxidized into carbon dioxide and [H.sub.2]O resulting in energy production.
Propionyl L-carnitine improvement of hypertrophied heart function is accompanied by an increase in carbohydrate oxidation.
There was an increase in the isovaleryl and 3-OH butyryl carnitine levels, whereas there was a decrease in the levels of acetyl, propionyl, and palmitoylcarnitine.
Proteins identified in these studies included albumin, ES1 carboxylesterase, propionyl and methylcrotonyl coenzyme A carboxylase-[alpha], and pyruvate carboxylase.
Propionyl CoA is converted to L-methylmalonyl CoA and the mutase (with vitamin B12 as coenzyme) converts this to succinyl CoA, which is part of the tricarboxylic acid (Krebs) cycle of metabolism.
To control the exotherm, the process as described suggests slow addition of propionyl chloride.
Our results suggest that additional metabolic modification to boost the levels of propionyl substrate in the plastids of alfalfa plants is required for efficient synthesis of PHB/V.
