The present disclosure relates generally to certain compounds, pharmaceutical compositions comprising said compounds, and methods of making and using said compounds and pharmaceutical compositions. The compounds and compositions provided herein may be used for the treatment or prevention of a Retroviridae infection, including an HIV infection.

Described are GCF-8 inhibitors of the formula (I), ##STR00001##
and pharmaceutically acceptable salts thereof, wherein n, R.sup.1, R.sup.2, R.sup.5, R.sup.6, X and Z are defined herein. Also provided are pharmaceutical compositions comprising the same. Such compounds and compositions are useful in methods for inhibiting GDF-8 in a cell and methods for treating a patient suffering from a disease or disorder, wherein the patient would therapeutically benefit from an increase in mass or strength of muscle tissue.

The present disclosure provides certain bicyclic heteroaryl compounds that inhibit ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) enzymatic activity and are therefore useful for the treatment of diseases and conditions modulated at least in part by ENPP1. In some embodiments, the bicyclic heteroaryl compounds includes those of Formula (I):

##STR00001##

Also provided herein are pharmaceutical compositions containing such compounds and processes for preparing such compounds.

The present invention relates to a phosphorus compound and the use thereof. Specifically, provided in the present invention is a compound of formula (I), or an optical isomer, racemate, solvate, pharmaceutically acceptable salt or deuterated compound thereof. The compound of the present invention has significant and excellent precision treatment effects on tumors that have low expression, no expression, low activity or no activity of mitochondrial permeability transition pores, low expression, no expression, low activity or no activity of peptidyl prolyl isomerase F, low expression or no expression of NNMT gene, high expression of DNA methylase, high expression of UHRFI, high methylation level at a nucleotide site in NNMT gene, and/or high methylation level of DNA at CpG site in NNMT gene region.
