There are some compounds that might target viral RNA rather than DNA. Adenosine N1-oxide 23 incorporated into the viral mRNA by viral RNA polymerase and selectively blocked vaccinia early gene expression.179 Marboran 14 possibly caused breakdown of vaccinia virus late mRNA, resulting in a cessation of late protein synthesis.179,180 Very recently, a series of very potent marboran derivatives has been identi ed by employing combinatorial library design. Compound 24, as an example, reduced vaccinia plaques in HFF cells with potency and selectivity 100-fold better than that of CDV.181

3.4 INHIBITORS OF SEVERE ACUTE RESPIRATORY SYNDROME (SARS) Recognizing the potentially high mortality and morbidity associated with SARS, in May 2003, NIAID convened a colloquium entitled SARS: Developing a Research Response to help identify research needs in SARS research clinical research, epidemiology, diagnostic, therapeutics, and vaccines and to help coordinate international research efforts.194 There are four areas being considered as SARS therapeutic research priorities: (1) drug screening (high throughput screening (HTS) assay and assay of existing compounds), (2) antiviral drug design (identi cation of viral targets, structural models of viral targets, design and synthesis of candidates), (3) immunomodulation and other therapies, and (4) preclinical (nonhuman primate and small-animal models) and clinical studies. In order to help accelerate the discovery of new leads for effective SARS countermeasures, NIAID offers a SARS Chip free to researchers for microarray analysis (see http:// www.niaid.nih.gov). A number of research initiatives and funding opportunities are also published on this website. In the area of drug screening, NIAID is participating in a project to screen compounds for in vitro activity against SARS associated coronavirus (SARS-CoV). The project was initiated in a collaborative effort with USAMRIID195 and continued with two domestic institutions under NIAID contracts. At this writing, NIAID is still actively accepting compounds (synthetic compounds and natural products) for screening against SARS-CoV under a con dentiality agreement (see http://www.niaid-aacf.org and http://www.niaid.nih.gov/dmid/ viral). Barnard and co-workers reported that b-D-N 4-hydroxycytidine 26 showed in vitro activity by both cytopathic effect (CPE) inhibition and virus yield reduction assays.196 Calpain inhibitors, such as calpain inhibitor VI 27, also were active in the same study. Combined with the data reported in other studies, it appeared that

pyrazofurin 6 showed activity in the CPE assay196 198 but not by using the virus yield reduction assay.196 Known inhibitors of IMPDH198 and SAH hydrolase196,198 were inactive. Other active compounds identi ed by screening include glycyrrhizin,197 niclosamide199 28, and valinomycin200 29. Ribavirin 1 was not active,196,198,201,202 although some might argue that it would work at high concentrations.203,204 However, in initial clinical studies, ribavirin offered no apparent bene ts.205 207 Representatives of approved antiviral drugs have also been selected and tested. In one report, except for some IFN preparations, all were shown to be inactive against the SARS-CoV in vitro, including HIV protease inhibitors.200,204 However, a team in Japan reported that nel navir was able to decrease the production of virions from Vero cells.208 A preliminary uncontrolled open clinical trial in Hong Kong suggested Kaletra (a coformulation

of protease inhibitors lopinavir and ritonavir for HIV treatment) might result in a favorable response when administered early.203,209 A summary of early clinical treatments of SARS can be found in a review by Fujii et al.207 Several types of IFN have been used clinically for viral infections; therefore, testing IFNs in vitro and in vivo would potentially lead to the discovery of drugs immediately available for this new disease. However, IFN activity could be speciesand cell-speci c; therefore, not all of the models are appropriate for evaluation.201, 202,204,210 As always, in vivo studies might be more predictable for the clinical ef cacy in humans.204 In macaques, it was shown that pegylated IFN-a protected type 1 pneumocytes against SARS-CoV infection.211 Other than monkeys, potential animal models for general drug evaluation are SARS virus infection in cats, ferrets, hamsters, and mice.212,213 The genomic sequence of the SARS-CoV has been published. The initial characterization of the viral genome showed this new virus is not closely related to any of the previously known CoVs,214 218 but distantly resembles group 2 CoVs.216,217,219,220 The initial products after translation of the SARS-CoV genome are autoproteolytically processed primarily by the main protease (Mpro, also called the 3C-like protease, 3CLpro) to release a number of nonstructural proteins, including the RNA-dependent RNA polymerase221 (RdRp) and the NTPase/helicase.218,222 These enzymes are attractive targets for HTS and drug design.223,224 Models of SARS-CoV Mpro have been constructed based on the crystal structures for group 1 viruses, that is, human coronavirus (HCoV) strain 229E and transmissible gastroenteritis virus (TGEV, a porcine CoV).225 229 Studies with these models suggested AG7088225,230 30 (an inhibitor of HRV 3Cpro) and L-700,417231 31 (an inhibitor of HIV protease) might be good starting points for drug
