(Sun et al., CN ‘254, citing the CAS Abstract for the compounds depicted above.)

Claim Rejections - 35 USC § 112(b)
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
Claim 6 is rejected under 35 U.S.C. 112(b) as failing to set forth the subject matter which the inventor or a joint inventor regards as the invention. Claim 6 recites the limitation "C5-C9 furanosyl". There is insufficient antecedent basis for this limitation in the claim.
Conclusion
Claims 1, 4, 6, and 9 are not allowed.
Claim 7 is objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
