Neferine is a natural alkaloid compound found in the seeds of the lotus plant (Nelumbo nucifera). It has been used in traditional medicine for centuries due to its various therapeutic properties. In recent years, neferine has gained attention in scientific research due to its potential applications in medicine, environmental research, and industrial processes.

TAK-779 is an antagonist of chemokine receptor 5 (CCR5), CCR2b, and CXC chemokine receptor 3 (CXCR3). It inhibits CCR5 and CXCR3 (IC50s = 236 and 369 nM, respectively, for mouse recombinant receptors expressed in 2B4 T cells) and CCR5 and CCR2b (IC50s = 1.4 and 27 nM, respectively, for human recombinant receptors expressed in CHO cells). TAK-779 inhibits the replication of clinical isolates of R5, but not X4, HIV-1 in human peripheral blood mononuclear cells (PBMCs; EC50s = 1.6-3.5 and >20,000 nM, respectively). TAK-779 (250 mg/animal per day) inhibits ovalbumin-induced increases in CCR5, CXCR3, IFN-γ, and TNF-α expression in mouse lung, as well as the number of total cells, lymphocytes, and eosinophils in bronchoalveolar lavage fluid (BALF), in a mouse model of asthma. It also increases intestinal allograft survival in a rat model of small intestine transplantation when administered at a dose of 10 mg/kg per day.
TAK-779 is a highly potent and selective nonpeptide CCR5 antagonist with a IC50 value of 1.4 nM in the binding assay, TAK-779 also inhibited the replication of macrophage (M)-tropic HIV-1 (Ba-L strain) in both MAGI-CCR5 cells and PBMCs with EC50 values of 1.2 and 3.7 nM, respectively. IC50 value: 1.4 nM Target: CCR5in vitro: TAK-779, a nonpeptide compound with a small molecular weight (Mr 531.13), antagonized the binding of RANTES (regulated on activation, normal T cell expressed and secreted) to CCR5-expressing Chinese hamster ovary cells and blocked CCR5-mediated Ca2+ signaling at nanomolar concentrations. The inhibition of beta-chemokine receptors by TAK-779 appeared to be specific to CCR5 because the compound antagonized CCR2b to a lesser extent but did not affect CCR1, CCR3, or CCR4. Consequently, TAK-779 displayed highly potent and selective inhibition of R5 HIV-1 replication without showing any cytotoxicity to the host cells. The compound inhibited the replication of R5 HIV-1 clinical isolates as well as a laboratory strain at a concentration of 1.6-3.7 nM in peripheral blood mononuclear cells, though it was totally inactive against T-cell line-tropic (CXCR4-using or X4) HIV-1. TAK-779 inhibits HIV-1 replication at the membrane fusion stage by blocking the interaction of the viral surface glycoprotein gp120 with CCR5. in vivo: Small intestines from DA rats were heterotopically transplanted into LEW rats. The recipients were treated with FK506 (1mg/kg/day, day 0-5) and TAK-779 (10mg/kg/day, day 0-10).
