results of the biological tests indicate that analogs with a methyl group alpha to the phosphate moiety (11c,d) exhibit a marked degree of stereoselectivity with regard to their anti-HIV activity. Also, replacement of the long alkyl chain with aromatic groups in the oxyalkyl ether phospholipid-AZT conjugates leads to substantially more potent compounds (11e-g) with an anti-HIV activity comparable to that

A new columnar cholesterogen based on the octasubstitutedphthalocyanine(PcH2), (+)-2,3,9,10,16,17,23,24-octakis[4-(dodecyloxy)-2-oxa-pentyl ]-phthalocyanine (1), is described. The chiral PcH2 1 exhibited classical cholesteric textures in which the transition of platelet to fan-shaped texture was observed (K\xrightarrow23°CM\xrightarrow158°CI). This is the first instance of columnar cholesterogen observed
