  • Publication number: 20240033244
    Abstract: A YTH N6-Methyladenosine RNA Binding Protein 1 (YTHDF1) attenuating agent, with a compound, and when bound to YTHDF1, the compound binds to amino acid residues 372-392, 479-494 and 526-535 of SEQ ID NO: 1. A modified antigen presenting cell (mAPC), with the mAPC being treated with a YTHDF1 attenuating agent. A composition, with a YTHDF1 attenuating agent, a mAPC treated with the YTHDF1 attenuating agent, and optionally a pharmaceutically acceptable carrier. A method for attenuating an activity of YTHDF1, by administering an effective amount of a YTHDF1 attenuating agent. A method for determining whether or not a candidate agent is a YTHDF1 attenuating agent, by contacting the candidate agent with a YTHDF1 mutant. A method for treating a disease, disorder or condition associated with an expression of an antigen in a subject in need thereof.

  • Patent number: 7419979
    Abstract: The invention relates to heterocyclic derivatives of formula (I), wherein R2 is amino, a group OR4 or a group —Y—R5 where R4 is hydrogen or C1-4alkyl, Y is C1-4alkylene, R5 is hydrogen, halo, hydroxy, C1-2alkoxy, C1-2alkoxyC1-2alkoxyC1-4, or a group NR7R8 where R7 and R8 are independently selected from hydrogen, C1-2alkyl, hydroxyC1-2alkyl or alkoxyC1-2alkyl, or R7 and R8 together with the nitrogen atom to which they are attached form a saturated 5-6-membered heterocyclic ring which optionally contains an additional heteroatom; n is one or two and each R1 is independently selected from halo, haloC1-2alkyl, hydroxy, oxo, amino, C1-2alkylamino or di-C1-2dialkylamino; or a pharmaceutically acceptable salt thereof. These compounds possess antithrombotic and anticoagulant properties and are accordingly useful in methods of treatment of humans or animals.
