indenopteridines and indolopteridines via their reaction with ninhydrin and isatin, respectively. The synthesised compounds were evaluated for antitumour activity against a human hepatocellular carcinoma cell line (HepG2), some showing antitumour activity comparable with 5-fluorouracil and imatinib.
Described is a A liquid colloidal pharmaceutical formulation of a type B lantibiotic for infusion or direct injection comprising a type B lantibiotic or a salt thereof, an isotonic aqueous solution comprising a sugar alcohol such as glycerol and/or a saccharide and optionally a buffer, wherein said final formulation for infusion or direct injection is clear of visual particulates.
The present disclosure relates to compounds of formula (II):
pharmaceutical compositions comprising same and use of the compounds and compositions for the treatment of microbial infection, particularly Methicillin-resistant
Staphylococcus aureus
(MRSA) infection.
Presently provided are methods for (a) modulating an activity of indoleamine 2,3-dioxygenase comprising contacting an indoleamine 2,3-dioxygenase with a modulation effective amount of a compound as described in one of the aspects described herein; (b) treating indoleamine 2,3-dioxygenase (IDO) mediated immunosuppression in a subject in need thereof, comprising administering an effective indoleamine 2,3-dioxygenase inhibiting amount of a compound as described in one of the aspects described herein; (c) treating a medical conditions that benefit from the inhibition of enzymatic activity of indoleamine-2,3-dioxygenase comprising administering an effective indoleamine 2,3-dioxygenase inhibiting amount of a compound as described in one of the aspects described herein; (d) enhancing the effectiveness of an anti-cancer treatment comprising administering an anti-cancer agent and a compound as described in one of the aspects described herein; (e) treating tumor-specific immunosuppression associated with cancer comprising administering an effective indoleamine 2,3-dioxygenase inhibiting amount of a compound as described in one of the aspects described herein; and (f) treating immunosuppression associated with an infectious disease, e.g., HIV-I infection, comprising administering an effective indoleamine 2,3-dioxygenase inhibiting amount a compound as described in one of the aspects described herein.
