Wild type adult male and female zebrafish, Danio rerio, were obtained from a commercial supplier (Ekkwill, Gibsonton, FL) and maintained in 30 gal aquaria at 28°C on a 14:10 light-dark cycle. Fertilized eggs were collected after natural spawning, washed, and distributed into 20 × 100 mm culture plates (Fisher Scientific). Embryos (150 embryos/50 ml egg water) were allowed to develop at 28°C on a 14L:10D cycle [36 ]. For developmental expression analysis embryos were collected after timed intervals: 2, 6, 12, 24, 48, 72, and 120 hours post-fertilization (hpf), quick-frozen on dry ice, and stored at -70°C until analysis (3 independent embryo pools, 50 embryos per pool, per time point from the same spawning group). For treatment expression analysis embryos were left untreated until 24 hpf and then exposed to 17β-estradiol (E2; 0.1 μM), testosterone (T; 1 μM), ICI 182,780 (ICI; 10 μM; Tocris Bioscience, Ellisville, MO), β-napthaflavone (BNF; 10 nM), or 2,3,7,8, tetrachlodibenzo-p-dioxin (TCDD; 1 nM; Ultra Scientific, N. Kingstown, RI) dissolved in dimethyl sulfoxide (DMSO). All chemicals were obtained from Sigma-Aldrich (St. Louis, MO) unless otherwise noted. Stock solutions of chemicals were added directly to egg water and replaced daily. In addition, embryos were treated with DMSO alone (final concentration, 0.0006%), EtOH alone (final concentration 0.0005%), or left untreated as a control. Embryos were collected at 96 hpf, quick-frozen on dry ice, and stored at -70°C until analysis (3 independent embryo pools per treatment). Treated embryo RNAs were used for both housekeeping gene expression analysis (Table 3) and gene of interest normalization (Figure 2). Tissues (brain, eye, heart, liver, muscle, gonad) were collected from adult male and female zebrafish, pooled by sex (3 pools per tissue type/sex, 5 fish per pool), quick-frozen on dry ice, and stored at -70°C. Adult fish were reproductively active stock from our breeding colony.

The Nkx3.1CreERT2/+ allele was generated by gene targeting using standard techniques; the Nkx3.1 null mutant mice have been previously described21 (link). R26R-lacZ and Pten conditional mutant mice were obtained from the Jackson Laboratory Induced Mutant Resource; the R26R-YFP mice were provided by Dr. Frank Costantini. All lines were maintained on a hybrid C57BL/6-129/Sv strain background.
Castration of adult male mice was performed using standard techniques. For tamoxifen induction of Cre activity in mice containing Nkx3.1CreERT2/+, mice were administered 9 mg/40 g tamoxifen for 4 consecutive days. For prostate regeneration, physiological levels of testosterone (1.875 µg/hr) were administered for four weeks by subcutaneous implantation of mini-osmotic pumps (Alzet)45 (link). When included, BrdU (100 mg/kg) was administered once daily during the first three days of regeneration. For single-cell transplantation, single YFP+ cells were isolated by mouth-pipetting under epifluorescence illumination from a dissociated prostate cell suspension obtained from castrated and tamoxifen-induced Nkx3.1CreERT2/+; R26R-YFP/+ mice. A single YFP+ cell (or YFP− cell as a control) was recombined with 2.5 × 105 rat urogenital sinus mesenchyme cells in a 10 µl collagen pad, followed by transplantation under the kidney capsule of nude mice and harvesting after 10–12 weeks.
Cryosections were stained with primary antibodies as listed in Supp. Table 5, and counterstained with TOPRO3 or DAPI (Invitrogen/Molecular Probes). Secondary antibodies were labeled with Alexa Fluor 488 , 555, or 594 (Invitrogen/Molecular Probes). Immunofluorescence staining was imaged using a Leica TCS5 spectral confocal microscope. Cell counting was performed manually using confocal photomicrographs with at least three animals for each experiment or genotype analyzed.

Bioavailable 25-hydroxyvitamin D was defined as circulating 25-hydroxyvitamin D not bound to vitamin D–binding protein, which is analogous to the definition of bioavailable testosterone.28 (link) Concentrations of bioavailable 25-hydroxyvitamin D were calculated in 1025 homozygotes, for whom we could use a single genotype-specific binding affinity constant on the basis of the presence of a single vitamin D–binding protein variant (see the Methods section in the Supplementary Appendix).22 (link) Calculated concentrations of bioavailable 25-hydroxyvitamin D were validated by direct measurement in a subgroup of homozygous participants with the use of a competitive radioligand-binding assay (see the Methods section and Fig. S2 and S3 in the Supplementary Appendix). Measured and calculated 25-hydroxyvitamin D concentrations were correlated (Pearson's r = 0.81 in 32 Gc1F homozygotes and 0.90 in 13 Gc1S homozygotes; P<0.001 for both relationships) (Fig. S4 in the Supplementary Appendix).

Process for Preparation
    • 1. Dutasteride was dissolved in ethanol
    • 2. Medium chain triglycerides and castor oil was added to contents of step 1 to form the solution.
    • 3. The above solution was filled into suitable containers.

The hair growth and hair thickness measurement of was conducted in Wistar rats. Wistar rats was divided into groups, each group having 13 animals. The study on the Wistar rats was conducted for 21 days. On day “0” of the study, fur over and around the flank organs of Wistar rats was shaved with electric clippers and the area of 2×2 cm was used for topical application of dutasteride compositions of examples 2 to 13 at a dose of 100 μl/kg of example 2 to Example 13 along with the compositions of reference example 1 (Finasteride oral at a dose of 0.1 mg/kg) for a period of 21 days once daily (every day between 10 and 11 pm). 100 μl of 1% testosterone was injected subcutaneously daily for 21 days (at 9 am every day) and effect (hair growth and thickness) was evaluated on 22nd day after sacrificing the animals. The normal control of shaved rats (without the administration of testosterone) was placed with a group consisting of 13 animals.

The change in hair growth was measured by visual scoring (hair growth score) on the 13 animals of each group and the mean was calculated. The visual scoring was calculated based on following parameters

    • Score 0: no hair growth observed
    • Score 1: less than 20% growth observed
    • Score 2: 20% to less than 40% growth observed
    • Score 3: 40% to less than 60% growth observed
    • Score 4: 60% to less than 80% growth observed
    • Score 5: 80% to 100% growth

The visual scoring of mean of 13 animals in each group treated with compositions of example 2 to 13 along with reference oral finasteride and normal control was depicted in Table 7.

The hair thickness was measured by Caslite hair analysing instrument attached to microscope at 200× magnification and results of hair thickness (μm) in each group treated with compositions of example 2 to 13 along with reference oral finasteride and normal control was depicted in Table 7.

The data in the Table 7 shows the hair growth score and hair thickness increased significantly in the Wistar rats of example 2 to 4, most preferably the composition of example 3 consisting of Dutasteride 0.022 wt % (equivalent to 0.02% w/v), Castor Oil 40 wt %, Medium chain triglycerides 30 wt % and Ethanol: qs to 100 wt % (about 30 wt %) has highest hair growth score and hair thickness when compared to the other formulations. The rapid onset of the effects of the above described composition for topical application of the present invention can significantly improve the treatment compliance. That is, in case of the conventional preparations (finasteride oral) the onset of effects is similar to that of the formulation as disclosed in example 3 at the reduced dosage with topical administration and has little side-effects, when compared to the oral finasteride.

Metabolism and Inhibition Profile of Mitapivat
Not available on PMC !

Example 1

CYP-enzyme phenotyping using human liver microsomes and recombinant CYP enzymes revealed that mitapivat sulfate was primarily metabolized by CYP3A4/5 (>90%), with minor contributions from CYP2C9, CYP2C8, and CYP1A2. There was evidence of metabolism-dependent inhibition of CYP2C19 (largely reversible) and CYP3A4 (largely irreversible). Mitapivat sulfate was found to be a substrate and inhibitor for P-gp but not for breast cancer resistance protein (BCRP) and was found to be a potential inducer of human CYP2B6 and CYP3A4. Mitapivat sulfate appeared to be a mild inhibitor of CYP2C8, CYP2C9, xYP2C19, CYP2D6, and CYP3A4/5 enzymes (testosterone 6β-hydroxylation), bile salts export pump (BSEP), organic anion transporting polypeptide (OATP)1B1, organic anion transporter (OAT)3, and organic cation transporter (OCT)2, and of uridine-5′-diphospho-glucuronosyltransferase (UGT) 1A3, 1A4, and 1A9. Mitapivat sulfate does not appear to be an inhibitor of multidrug resistance-associated protein (MRP)2, MRP3, OATP1B3, and OAT1. The metabolite was found to be a mild inhibitor of CYP2C9 and CYP2C19 and was not an inhibitor of P-gp or BCRP under tested concentrations.

CYP3A4 Inhibition Assay Protocol
Incubations were performed with 0.1 mg/mL human liver microsomes (purchased from BD Gentest as a pooled batch from 150 donors) in a final incubation volume of 0.25 mL. The incubation medium contained 0.05 M phosphate buffer (pH 7.4) containing an NADPH regenerating system (including 1.3 mM NADP, 3.3 mM glucose 6-phosphate,3.3 mM MgCl2, and 1.0 U/mL glucose 6-phosphate dehydrogenase). Probe CYP3A4 substrates (midazolam at 3 μM and testosterone at 50 μM), were incubated for 10 and 30 min, respectively, with increasing concentrations of GM, MGM or CGM (concentration range: 1 - 30 μM). The reaction was stopped by adding acetonitrile to precipitate the proteins. The incubation mixtures were then centrifuged for 5 min at 10,000 × g, and an aliquot of the supernatant was analyzed using high-performance liquid chromatography coupled to mass spectrometry for the assessment of 1’-hydroxymidazolam and 6β-hydroxytestosterone metabolite formation.
