Based on the promising activity of an indole-3-carboxamide derivative, a nonphenolic analog of mycophenolic acid (MPA), we report herein the synthesis of a compound containing two important features for the activity of MPA, the ring methoxy and methyl. The synthesis was accomplished using two strategies; a method dependent on stepwise building of the hexenoate side chain followed by the indolecarboxamide ring system, and a convergent route that depended on 1,3-sigmatropic rearrangement as a key step. Docking experiments on both Chinese Hamster and Human Type-II inosine monophosphate dehydrogenase (IMPDH) showed that this compound has potential binding interactions with the NAD site. The analogs showed no activity against MCF7-S, MCF7-R, or IGR-OV1 cancer cells.

Oropouche virus (OROV), an emerging arbovirus, poses a significant public health challenge in tropical and subtropical regions, with no licensed vaccines or antiviral therapies currently available. This review explores recent advancements in therapeutic strategies and vaccine development for OROV, focusing on molecular mechanisms of viral replication, identification of potential antiviral targets, and the role of immunotherapy in managing infections. Promising antiviral candidates, including ribavirin, mycophenolic acid, and interferon, have demonstrated efficacy in in vitro studies, offering a foundation for further investigation.

BK polyomavirus remains a vexing issue in kidney transplantation. There are no antiviral drugs, and solely reducing immunosuppression is recommended for management. However, evidence from randomized controlled studies lacks defining clearance of BK polyomavirus-DNAemia and/or nephropathy as a primary outcome.

Introduction: Mycophenolate mofetil (MMF) is an immunosuppressive drug administered in the management of both autoimmune diseases and organ transplantation. The main aims of the study were: (a) to obtain information regarding the safety of using MMF in respect of its effect on normal T and B cells in lymphoid tissues; (b) to investigate whether the generation of inducible Foxp3-expressing regulatory T cells (Treg) might constitute additional mechanisms underlying the immunosuppressive properties of MMF.
Methods: The effect of MMF ( studies) and its active metabolite, mycophenolic acid, ( studies) on murine CD4 and CD8 T cells as well as B cells was determined, regarding: (a) absolute count, proliferation and apoptosis of these cells ( studies); (b) absolute count of these cells in the head and neck lymph nodes, mesenteric lymph nodes and the spleen ( studies).
