EXAMPLE 89 ##STR118##
To a suspension of well-grinded mixture of 10 g of neutral alminum oxide and 3.3 g of 86% KOH in 40 ml of dioxane is added 1.22 g (10 mmol) of isonicotinamide. The mixture is mixed with 1.77 g (5 mmol) of tetraprenyl bromide a-1 and stirred at 50.degree..about.60.degree. C. for 4 hours. The reaction mixture is filtered and concentrated under reduced pressure. The residue is extracted with 50 ml of AcOEt, washed twice with 50 ml of water, dried over anhydrous sodium sulfate, and evaporated under reduced pressure. The resulting oil is purified by silica-gel column chromatography and eluted with AcOEt to give 1.06 g of the titled compound I-22. Yield: 54%.
EXAMPLE 90
1-(N-3,7,11,15-Tetramethyl-2,6,10,14-hexadecatetraenyl)thiocarbamoyl morpholine I-88 ##STR119##
To a solution of 664 mg (2 mmol) of N-tetraprenyl isothiocyanate g-l in 20 ml of CH.sub.2 Cl.sub.2 is added 192 mg (2.2 mmol) of morpholine. The mixture is heated under reflux for about 2 hours. The reaction mixture is washed twice with 20 ml of water, dried over anhydrous sodium sulfate, and evaporated under reduced pressure. The residual oil is purified by silica-gel column chromatography and eluted with Et.sub.2 O:hexane (10:1 v/v) to give 812 mg of the objective compound I-88. Yield: 96.9%.
EXAMPLE 91
N-(4-Pyridylmethyl)-N'-(3,7,11,15-tetramethyl-2,6,10,14-hexadecatetraenyl)thiourea I-89 ##STR120##
664 mg (2 mmol) of N-Tetraprenyl isothiocyanate g-l and 238 mg (2.2 mmol) of 4-aminomethyl pyridine are allowed to react in the same manner as in Example 90 and the product is purified by silica-gel column chromatography and eluted with AcOEt:MeOH (15:1 v/v) to give 791 mg of the titled compound I-89 as yellowish oil. Yield: 89.9%.
EXAMPLE 92
N-4-Pyridyl-N'-(3,7,11,15-tetraprenyl-2,6,10,14-hexadecatetraenyl)thiourea I-90 ##STR121##
A mixture of 311 mg (3.3 mmol) of 4-aminopyridine, 10 ml of anhydrous dimethylformamide, 132 mg of NaH is stirred at room temperature for 1 hour. The mixture is mixed with 995 mg (3 mmol) of N-tetraprenyl isothiocyanate, stirred at 100.degree. C. for another 1 hour, and concentrated under reduced pressure. The residue is extracted with 50 ml of AcOEt, washed with water (50 ml.times.2), dried over anhydrous sodium sulfate, and evaporated under reduced pressure. The resulting residue is purified by silica-gel column chromatography and eluted with AcOEt:MeOH (20:1 v/v) to give 815 mg of the titled compound I-90 as colorless oil. Yield: 63.8%.
EXAMPLE 93
N-(3,7,11,15-Tetraprenyl-2,6,10,14-hexadecatetraenyl)thionicotinamide I-91 ##STR122##
To a solution of 789 mg (2 mmol) of the compound I-21 in 20 ml of anhydrous toluene is added 1.62 g (4 mmol) of Rawesson's Reagent. The mixture is heated under reflux for 1 hour, mixed with 20 ml of saturated aqueous NaHCO.sub.3. The reaction mixture is stirred at room temperature for 1 hour. The CH.sub.2 Cl.sub.2 layer is washed twice with 20 ml of water, dried over anhydrous sodium sulfate, and evaporated under reduced pressure. The residual oil is purified by silica-gel column chromatography and eluted with AcOEt:Et.sub.2 O (1:2 v/v) to give 569 mg of the titled compound I-91 as yellowish oil. Yield: 69.3%.
EXAMPLE 94
N-(3,7,11,15-Tetramethyl-2,6,10,14-hexadecatetraenyl)thioisonicotinamide I-92 ##STR123##
The reaction is carried out in the same manner as in Example 93 by using 737 mg (1.87 mmol) of the compound I-22, 1.54 g (3.8 mmol) of Rawesson's Reagent, and 20 ml of anhydrous toluene. The product is purified by silica-gel column chromatography and eluted with Et.sub.2 O:hexane (2:1 v/v) to give 585 mg of the titled compound I-92 as yellowish oil. Yield: 76.2%.

Effect
Experiment 1
Method
Male SD rats, weighing 200-300 g, were allowed to fast for 24 hours. One milliliter of 60% ethanol (v/v) in 150 mM hydrochloric acid was given orally 1 hour after oral or intraperitoneal administration of test compound as a suspension in 5% gum arabic, and the animals were killed with an overdose of ether 1 hour later. The stomachs were removed and opened along the greater curvature. The total length (mm) of each lesion was measured for use as the lesion index and inhibition (%) of lesion formation by the test compound was calculated by comparing with that of 5% gum arabic as control.
Result
The number of the test compounds corresponds to the compound number used in Examples.
Geranylgeranylacetone (hereinafter abbreviated as GGA) was employed as a reference compound.

Experiment 2
Method
Male Jcl SD rats (body weight; about 300 g) were fast for 24 hours and anesthetized by urethane. Cannula was put into the trachea and into a jugular vein. After midline laparotomy, perfusion cannulae were introduced into the stomach through the pylorus and the esophagus. The animal was perfused with saline (1 ml/min) at 37.degree. C. through the esophagus cannula. Perfusate was collected every 15 minutes through the pylorus cannula and titrated with 0.01N sodium hydroxide to measure acid secretion. Histamine dihydrochloride (3 mg/kg/hr) was infused through the jugular vein cannula and the test compound was administered intraduodenaly 90 minutes later. Acid output in perfusate every 15 minutes was measured in the same manner as described above. The rate of maximum inhibition (%) of acid secretion was calculated during 90 minutes after administration of the test compound compared with the acid output just before administration of the test compound.
