A new species of (Crustacea, Thecostraca, Ascothoracida) parasitic in an antipatharian from Green Island, Taiwan, with notes on its morphology.

A new ascothoracidan species has been discovered off Taiwan in the north part of the west Pacific at SCUBA depths. Twelve specimens including both sexes of the new species, described herein as , were collected from colonies of the antipatharian Myriopathes cf. japonica Brook, 1889.

Gorgonolaureus bicornutus sp. nov (Crustacea: Thecostraca: Ascothoracida) from off South-East Taiwan with notes on morphology and distribution.

A new ascothoracidan species, Gorgonolaureus bicornutus sp. nov., has been discovered off south-eastern Taiwan at a depth of 227 m.

5-Arylethynyl-2'-deoxyuridines, compounds active against HSV-1.

Three new 5-arylethynyl-2'-deoxyuridines containing bulky aryls have been prepared and tested against HSV-1 in Vero cells. The introduction of a substituent in the phenyl group of an inactive compound, 5-phenylethynyl-2'-deoxyuridine, leads to the appearance of anti-HSV properties. The most active compounds are those containing a polycyclic aromatic hydrocarbon residue attached to the 5 position of 2'-deoxyuridine through a rigid triple bond.

[Antiherpetic activity of 5-alkynyl derivatives of 2'-deoxyuridine].

A series of new 5-alkynyl-2'-deoxyuridines have been synthesized and their antiherpetic activity was tested in the cultured Vero cells on a model of herpes simplex virus type 1, including its acyclovir-resistant strains. Some test compounds were found to have a significant specific antiherpetic activity. Nucleoside XIV showed the greatest activity.

Synthesis and evaluation of anti-HSV activity of new 5-alkynyl-2'-deoxyuridines.

Eight 5-alkynyl-2'deoxyuridines containing different bulky substituents have been prepared and tested against HSV-1 in Vero cells. The compounds show positive antiviral activity. There is no obvious correlation between activity and substituent size.
