Methods Seventy-five SD rats were randomized into five groups: normal, model, iodine glycerin (20 g/L), high-dose SP (200 g/L) and low-dose SP (100 g/L). The experimental periodontitis rat models were established by ligating molars with steel wire combined with intramuscularly injection of prednisolone (1.25mg, 8 times). Except that the model and normal groups were treated by applying saline, the other groups were treated by applying the corresponding drugs 0.5 mL to the peridentium, tid for 10 days. After treatment, debris index, probe depth and bleeding rate during probing were investigated and the pathological changes of periodontal tissues were also observed.

The synthetic route starts from penicillin G, peroxyacetic acid(8.5%) as Oxidizing Agent to get penicillin G sulfoxide; esterifided with p-nitrobenzyl bromine to synthesize penicillin G sulfoxide ester; we synthesize 3-exomethylenecepham sulfoxide ester with phthalimide potassium and 4A molecular sieve as acid scavenger to open the ring, SnCl_4 as catalyzation to close the ring. The yield is over 60%.
