The crystal structure of the title compound, 1,1 dichloro 3 dichloro 3 dichloromethyl 1a,3 diphenyl 1a,2,3,4 tetrahydro 1H azirino 1,2 a 1,5 benzodiazepine (C 23 H 18 Cl 4N 2, M r =4...The crystal structure of the title compound, 1,1 dichloro 3 dichloro 3 dichloromethyl 1a,3 diphenyl 1a,2,3,4 tetrahydro 1H azirino 1,2 a 1,5 benzodiazepine (C 23 H 18 Cl 4N 2, M r =464.22) was crystallized in triclinic, space group P 1, with cell dimensions a=9.621(7), b=9.694(9), c=12.669(6) , α=107.99(5)°, β=101.42(5)°, γ=69.94(6)°, V=1050.2(4) 3, Z=2, D c =1.468 g/cm 3 , Cu Kα(λ=1.5418 ). F(000)=1816, μ =2.44 mm -1 . The structure was solved by direct methods and refined by full matrix least squares method, and the final crystallographic discrepancy factor is 0.063 for 2555 observed reflections. The molecular backbone is a tricyclic system with the central seven membered 1,5 diazepine ring in twisted boat like conformation and cis fused to both aziridine ring and benzene ring.展开更多

The sequence of BPP, which was first reported, was determined by DABITC/PITC double coupling method, and confirmed by chemical synthesis. Some analogues of BPP were also synthesized by SPPS Method. The effect of these peptides on spleen lymphocytes from mice of Kunming inbred line and on release of SIL-2R from human lymphocytes were studied. The results showed that these peptides exhibit certain immune activity.展开更多
