Abstract: The invention generally relates to cell-specific expression vectors. It particularly relates to targeted gene therapy using recombinant expression vectors and particularly adenovirus vectors. The invention specifically relates to replication-conditional expression vectors and methods for using them. Such vectors are able to selectively replicate in a target cell or tissue to provide a therapeutic benefit in a tissue from the presence of the vector per se or from one or more heterologous gene products expressed from the vector and distributed throughout the tissue. In such vectors, a gene essential for replication is placed under the control of a heterologous tissue-specific transcriptional regulatory sequence. Thus, replication is conditioned on the presence of a factor(s) that induces transcription or the absence of a factor(s) that inhibits transcription of the gene by means of the transcriptional regulatory sequence with this vector; therefore, a target tissue can be selectively treated.

Abstract: A pharmaceutical product comprising a nucleoside analogue active against herpes simplex virus, such as acyclovir/valaciclovir or penciclorivir/famciclovir, and an immunosuppressant, as a combined preparation for simultaneous, separate or sequential use in the treatment and/or prevention of herpes simplex virus infections.

Abstract: One of the problems facing transplantation procedures today is the availability of organs suitable for transplantation. A way around the lack of organs, it to harvest organs from animals. However, immune reactions between discordant donor and recipient mammals presents a major obstacle in such transplantation procedures. The production of transgenic non-human mammals expressing a DNA sequence encoding an homologous complement restriction factor or factors of a discordant mammalian species such that the expression of the DNA sequence would prevent xenograft rejection by the host mammal's immune system would provide organs, tissues and cells for transplantation.

Abstract: The present invention is directed to the use of a compound of Formula (A), or a bioprecursor, or a pharmaceutically acceptable salt, phosphate ester and/or acyl derivative of either of the foregoing in the manufacture of a medicament for use in the treatment, including prophylaxis of HHV-8 infection.

Abstract: Use of a compound of formula I wherein R1 is an optionally substituted straight- or branched carbon chain having 12 to 22 carbon atoms which may be optionally interrupted by an optionally substituted phenylene, and each of R2, R3, R4 and R5, independently, is H or lower alkyl, in free form or in pharmaceutically acceptable salt form, in the prevention or treatment of chronic rejection in a recipient of organ or tissue allo- or xenotransplant, or of acute rejection in a xenograft transplant recipient.

Abstract: Conventionally, animal tissue from one species can only be transplanted into another species when the species are concordant; otherwise, hyperimmune rejection ensues. In this invention, donor tissue is modified, for example by being transgenic, to express or otherwise be in association with one or more substances, referred to as homologous complement restriction factors (HCRFs), which are active in the recipient species to prevent the complete activation of complement and therefore rejection. The invention is in part based on the discovery that the alternative pathway of complement activation, rather than the classical pathway, is responsible for hyperacute discordant xenograft rejection.

Abstract: An oil-in-water topical pharmaceutical formulation or an aqueous formulation for the treatment of virus infections of the skin or mucosa, comprising at least 30% of propylene glycol and solubilized penciclovir.

Abstract: The invention provides a method of rearranging a compound of formula (I), wherein R and R′ are selected independently from hydrogen and C1-12alkyl; and R1 and R2 are selected independently from hydrogen, hydroxy, halo, C1-12alkyl- or aryl carbonate, amino, mono- or di-C1-12alkylamino, C1-12alkyl or arylamido, C1-12alkyl- or arylcarbonyl, C1-12alkyl- or arylcarboxy, C1-12alkyl- or arylcarbamoyl, C1-12alkyl, C2-12alkenyl, C2-12alkynyl, aryl, heteroaryl, C1-12alkoxy, aryloxy, azido, C1-12alkyl- or arylthio, C1-12alkyl- or arylsulfonyl, C1-12alkyl- or arylsilyl, C1-12alkyl- or arylphosphoryl, and phosphato; to form a compound of formula (II), wherein R, R′, R1 and R2 are as defined for formula (I); said method comprising treating the compound of formula (I) with a palladium (0) catalyst and a (diphenylphosphino)nC1-6 alkane, wherein n is an integer of 1-6. The invention also provides methods of R making penciclovir and famciclovir using this rearrangement reaction.

Abstract: An expression system for producing and isolating large quantities of protein. The system comprises an expression vector containing a first coding region which codes for glutathione-S-transferase operatively connected to a baculovirus promoter, a second coding region in-frame with the first coding region, and a restriction region downstream of the first coding region, into which the second coding region is inserted. A fusion protein encoded by the first and second coding region is produced by expression of the vector. Examples of this second coding region include Lck, LynB, Syk, Blk, Fyn, and Yes. A process for expression of the vector in a host cell such as Spodoptera frugiperda is also included.
