  • For the purpose of developing of anticariogenic agents, P-phenylphenol derivatives were synthesized and determined their antibacterial activities against a cariogenic bacterium, Streptococcus mutans. Among synthetic compounds, 2-nitro-6-bromo-p-phenylphenol showed as potent antibacterial activity as magnolol and honokiol.

  • Naturally occurring diallyldihydroxybiphenyl compounds, magnolol and honokiol were reported to have potent antibacterial activities against most of Gram positive bacteria (1-4). To developmore potent antibacterial agents, some allyhydroxybiphenyl derivatives were synthesized from the starting compounds, p-phenyl-phenol (I) p-phenylphenol (IV), o, o-biphenol (VII) and p. p'-biphenol (XII). Among the newly synthesized compounds (III, VI, IX, XI, XIV and XVI), the antibacterial activities of 2-allyl-p-phenylphenol (VI), 6-ally-o, 0'-biphenol (IX), 2, 2'-diallyl-o, o'-biphenol (XIV) and 2, 2', 6-triallyl-p, p'-biphenol (XIV) were more potent than those of magnolol and bonokiol against a cariogenic bacterium, Stroptococcus matans ATCC OMZ 176.

  • Tetrahomodioxa p-phenylcalix(4)arene dihexylether (C/sub 66/H/sub 68/O/sub 6/)를 합성하여 분자 및 결정 구조를 X-선 회절법으로 연구하였다. p-Phenylphenol의 탈수, 고리화 반응으로 만든 tetrahomodioxa p-phenylcalix(4)arene을 DMF에서 NaH와 hexyl iodide를 환류시켜 합성하였다. 결정은 사방정계이고 공간군은 P2₁2₁2₁, a =9.764(2), b = 16.167(2), c = 32.994(3) Å, V=5208(1) ų, Z= 4, Dc=1.221 gcm/sup -3/이다. 직접법으로 구조를 해석하였으며, 최소자승법으로 정밀화하여 최종 신뢰도 R 값은 2009개의 회절 반점에 대해 0.070 이었다. 이 분자는 마주 보고 있는 phenyl group 두 쌍이 거의 평행을 이루며, C-1,2-alternate conformation이고, lower rim의 1,3 위치에 hexyl 기가 치환된 비대칭 homooxacalixarene이다.
