Abstract

PURPOSE: To obtain an antiviral agent, containing a new diterpene derivative and having especially anti-HIV actions. CONSTITUTION: This medicine contains about 0.01-99.99% diterpene derivative (or its stereoisomer) of formula I [R<1> is H or a 1-20C acyloxy; R<2> and R<5> are each H or pivalyl and R<3> and R<4> are each H when R<1> is H; R<2> to R<5> are each H, a 1-20C acyl, a (substituted)benzoyl, etc., when R<1> is the 1-20C acyloxy] as an active ingredient. For example, the derivative of formula II [R<11> is H or a 1-20C acyloxy; R<12> is pivalyl when R<11> is H and R<12> is a 1-20C acyl, a (substituted)benzoyl, etc., when R<11> is the 1-20C acyloxy] is obtained by reacting a diterpene derivative of formula III with a halogen compound of the formula R<13> X [<13> is a 1-20C acyl, a (substituted)benzoyl, etc.] in the presence of a base such as pyridine in or without a solvent such as diethyl ether at 0-200 deg.C (preferably 10-120 deg.C) for 1hr to several days (preferably 2hr to 2 days).

The ethanol extract was concentrated under reduced pressure to obtain 810 g of an ethanol extract.

Fractionation was carried out using 74.4 g of this ethanol extract. First, the ethanol extract was fractionated by liquid-liquid partition. That is, the mixture was partitioned in two layers of methanol-hexane, the hexane layer was taken out, the remaining methanolic water and ethyl acetate were added and partitioned, and the ethyl acetate layer and the water-methanol layer were taken out. The ethyl acetate layer was concentrated under reduced pressure to give a brown viscous oil (17.78 g). This is a silica gel column chromatography (WAKOGEL C

When the NMR of the 4th fraction (2.158 g) was measured, a peak of olefin protons around δ6 ppm, which was characteristic of ingenol derivatives and 13-oxyingenol derivatives, could be observed. Therefore, it was decided to hydrolyze the fourth fraction and then isolate and purify 13-oxyingenol. That is, the fourth fraction was dissolved in 50 mL of methanol,
5% aqueous NaOH solution was added, and the mixture was stirred at room temperature for 1 hour.
The reaction mixture was poured into water and extracted with chloroform. The chloroform layer was washed successively with a 1N NaOH aqueous solution and saturated brine, and dried over MgSO 4 . After removing MgSO 4 by filtration, the mixture was concentrated under reduced pressure to obtain 1.690 g of a residue.

The mixture was stirred at room temperature for 20 hours. The reaction mixture was diluted with diethyl ether, which was washed successively with water, 1N NaOH aqueous solution and saturated brine, and dried over MgSO 4 . After filtering off MgSO 4 , concentration under reduced pressure gave 16.1 mg of residue.

Infected with 0.02 HIV-1 cells per cell,
Immediately, a predetermined amount of the sample containing the compound of the present invention was added, and the mixture was cultured at 37 ° C. Five days after the culture, the living cells were measured by the MTT method to determine the compound concentration (EC 50 ) required to prevent the cell death of MT-4 cells by 50%. Further, the cells were cultured in the same manner as above without being infected with HIV-1, and the compound concentration (CC 50 ) at which 50% of MT-4 cells were killed was determined. In addition, EC 50 and C
C 50 to S. I. (= CC 50 / EC 50 ) was determined. The obtained results are shown in Table 2.
