Description:	Teriparatide is a PHT agonist, with an IC50 of 2 nM in HEK293 cells. Sequence: Ser-Val-Ser-Glu-Ile-Gln-Leu-Met-His-Asn-Leu-Gly-Lys-His-Leu-Asn-Ser-Met-Glu-Arg-Val-Glu-Trp-Leu-Arg-Lys-Lys-Leu-Gln-Asp-Val-His-Asn-Phe.
Target:	IC50: 2 nM (PTH)[1].
In Vivo:	Trabecular bone calcium and dry weight of the distal femur increased significantly in Teriparatide-treated animals. The increase in trabecular calcium compared with vehicle control occurred as early as 1 week after initiation of treatment with a 35% and 45% increase, respectively, for 10 μg/kg and 40 μg/kg Teriparatide. Similar results were observed for trabecular dry weight. After 4 weeks of treatment with 10 mg/kg or 40 mg/kg Teriparatide, trabecular calcium increased significantly by 70% and 123%, respectively, compared with the vehicle and by 73%[1]. The 4-week Teriparatide administration increase the pore ratio, number, and density as well as the cortical area, thickness, and bone mineral content (BMC), without significant influencing the volumetric bone mineral density (BMD). The 4-week Teriparatide administration + 8-week vehicle administration decrease the pore ratio, number, and density as well as the cortical area and thickness, compared with the 4-week Teriparatide administration, but the pore ratio, cortical area, and thickness are still higher compared with the 12-week vehicle administration. The 4-week Teriparatide administration + 8-week higherdose IBN administration increase the cortical area, thickness, BMC, and volumetricBMD and decrease the pore ratio, but not the pore number or density, compared with the 4-week Teriparatide administration + 8-week vehicle administration[2].
Animal Administration:	Rats[1] Teriparatide is administered daily to 4-week-old male rats for 1, 2, or 4 weeks with different concentrations (10, 40 μg/kg). At each time point, longitudinal growth, expressed as maximal femur length, is not statistically different between treated and control rats or between the two different treatment groups. Midfemur diaphyseal widths also do not differ between groups[1]. Rabbits[2] Forty-two female New Zealand white rabbits (17-21 weeks old) are used throughout the study. After 10 days of adaptation to their new environment, the rabbits (18-22 weeks old) are randomized into six groups of 7 animals each using the stratified weight method, as follows: 4-week vehicle administration group (4W-Veh), 4-week Teriparatide (TPTD) administration group (4W-Teriparatide: 20 μg/kg, subcutaneously [s.c.], daily), 12-week vehicle administration group (12W-Veh), 4-week Teriparatide administration + 8-week vehicle administration group (4W-Teriparatide + 8W-Veh), 4-week Teriparatide administration + 8-week lower-dose IBN administration group (4W-Teriparatide + 8W-IBN(L): 20 μg/kg of IBN, s.c., every 4 weeks), and 4-week Teriparatide administration + 8-week higher-dose IBN administration group (4W-Teriparatide + 8W-IBN(H): 100 μg/kg of IBN, s.c., every 4 weeks)[2].

DC59010	C14-4 (C14-494,Lipid B-4,Lipid B4)	C14-4 (C14-494,Lipid B-4,Lipid B4) is a novel ionizable lipid with the highest T-cell transfection efficiency and low cytotoxicity.The C14-4 ionizable lipid has been explored for CAR-T therapy.To screen the excellent formulations for mRNA delivery, a lipid library of 24 ionizable lipids was constructed to make iLNPs, which were used to deliver luciferase mRNA into Jurkat cells.[115] The optimal iLNPs formulation was C14-4 iLNPs (C14-4 ionizable lipid, DOPE, chol, and PEG at a molar ratio of 35%, 16%, 46.5%, and 2.5%) (Figure 6c). The optimal dose of luciferase mRNA for C14-4 iLNPs was 30 ng. Compared with electroporated CAR T cells, the CAR T cells engineered via C14-4 iLNPs showed potent cancer-killing activity when they were cocultured with Nalm-6 acute lymphoblastic leukemia cells. To obtain a safer and more effective CAR mRNA delivery vehicle, the orthogonal design provided 256 potential formulations, and 16 representative iLNPs formulations were evaluated.Through evaluating the safety, delivery efficiency, and transfection efficiency of 16 iLNPs, the formulation B10 (C14-4 ionizable lipid, DOPE, chol, PEG at a molar ratio of 40%, 30%, 25%, and 2.5%) was screened out as the optimal performing formulation. The luciferase expression based on B10 formulation was increased threefold than the initial formulation. Reducing the accumulation and clearance of iLNPs in the liver can increase the expression of CAR mRNA in T cells, further improving the therapeutic effect of CAR-T. Studies have shown that cholesterol analogs can alter the mechanisms of intracellular circulation and enhance the delivery of mRNA, which may be related to the reduced recognition of iLNPs by the Niemann Pick C1 (NPC1) enzyme.The addition of a hydroxyl group to various locations in the cholesterol molecule can alter the binding kinetics between the modified cholesterol and NPC1, and reduced NPC1 recognition of cholesterol. The results showed that replacement of 25% and 50% 7 α-hydroxycholesterol for cholesterol in iLNPs improved mRNA delivery to primary human T cells in vitro by 1.8-fold and twofold, respectively.C14-4 is one of the ionizable lipids to efficiently deliver mRNA to Jurkat cells or primary human T cells. It will effectively promote the development of mRNA delivery by iLNPs for CAR-T therapy.
